Another Flap Over Dinosaur Feathers

first_img(Visited 46 times, 1 visits today)FacebookTwitterPinterestSave分享0 The first North American “feathered dinosaur” has put the media in a frenzy of celebration over questionable data.Three Canadians from Alberta took a look at old fossils of the “ostrich-mimic” dinosaur Ornithomimus stored in drawers at the Royal Tyrrell Museum of Palaeontology, and found fibrous impressions in the sandstone they interpret as feathers on the forewings.  News media immediately launched an artwork-laden campaign of touting this as the first “feathered dinosaur” found outside of China and Germany (Archaeopteryx being the German claim).As soon as the paper hit Science, as if on cue, Science Daily, PhysOrg, Live Science, the BBC News and the other usual suspects put up Julius Csotonyi’s creative artwork from their paper in their coverage with no critique or alternative analysis whatsoever.  Strangely, the popular reports added colorful backgrounds of sky and forest that were not present in the small image in the paper, though the University of Calgary press release came fully illustrated.  Moreover, the popular reports simply parroted the interpretation of the feathers as courtship displays, while soft-pedaling the problems.And there are problems.  First of all, the rock impressions of the “feathers” consist mostly of straight lines that look nothing like the pennaceous flight feathers of Archaeopteryx.  One will read Zelenitsky’s paper in vain for mention the words vane, pennaceous or barbule in the main paper or supplemental information, except (for barbule) in the following curious circumlocution, “Evidence of shafted feathers {i.e., feathers with a rigid shaft, with or without interlocking barbules [type 3 feathers or higher (11, 12)]} is preserved on the forelimb bones of an adult Ornithomimus skeleton.”  The authors call them “filamentous feathers” with filamentous meaning just that: a filament or shaft, much simpler than the complex vanes of true feathers with their barbs, barbules and interlocking hooks.So do the photos of the fossils show these to be true feathers?  No; even the interpretive sketches show nothing but straight lines, with the exception of a very few tiny fragments shaped like a U or curve that, with copious imagination, might be interpreted as hooks for something, though they are disconnected from any barbs or barbules, which are not evident anywhere.  Further, these “feathers” are not connected to the skeleton, being separated by a centimeter or more at various angles from parallel to almost perpendicular.  They look like scratches in the rock.  Since the fossils were buried in sandstone instead of the limestone of German and Chinese fossils, license has to be taken to assume that such delicate impressions could be made in sandstone in this singular instance.  The authors tempted other researchers to go on a search for feathers in sandstone.Other problems present themselves with the “feathered dinosaur” interpretation.  All the others were theropods in the group of saurischian (lizard-hipped) dinosaurs.  This one is completely outside that group.  It’s in the ornithischian (bird-hipped) branch.  While that might sound like a plus for dinosaur-to-bird evolution theories, it would require evolutionists to postulate the emergence of the feather-whatever-things in the common ancestor long before flight supposedly evolved.  These feathers had nothing to do with the evolution of  flight.  The creatures were far too heavy for that.  The authors admit this by postulating that the “filamentous feathers” (found only on the adult) were used for courtship display.There was only one adult that showed the scratch marks, and one juvenile without them.  A third had markings on the bone.  Notice how their handling of the specimens adds to the confusion:Preparation of specimens with feathersTwo ornithomimosaur skeletons associated with fossilized feathers, TMP 2008.70.1 and TMP 2009.110.1, were preserved in hard, cemented sandstone blocks and prepared in 2008-2009. Preparation of this matrix could only be achieved with a Chicago Pneumatic (CP-9361) airscribe. In order to expose the feathers preserved in TMP 2008.70.1, the rock had to break along the parting plane on which the structures are preserved. In many instances, the rock did not break along that plane, resulting in the partial destruction of some filaments. In TMP 2009.110.1, the parting plane fortunately occurred between the sandstone and the ferruginous coating, revealing the presence of filamentous feathers in the ironstone.A third skeleton (TMP 1995.110.1) was preserved in a siltstone to fine-grained sandstone and displays markings on the left radius and ulna, inferred to be traces left by shafted feathers.  Although the markings were first discovered on the bones during specimen preparation in 1995, feathers impressions were not found in the matrix at the time.  (Supplemental Information, p. 2).The photo of 1995.110.1 shows only dark criss-cross markings on the bone that they “inferred to be traces left by shafted feathers.”  They don’t bear any resemblance to actual feathers.  This means that only one fossil had the carbonized impressions extending from parts of its forelimbs at some distance from the bones, leaving plenty of leeway to speculate about what they were, or whether they had any connection to the animal.  Yet their artwork shows the adult with fully-fledged wing feathers, barbs, barbules and all, and even multiple colors!Even the language they use to describe the “feathers” is couched with escape hatches.  “Their distribution and orientation are similar to the insertion pattern of covert feathers (20, 21), which form the bulk of the feather covering in modern bird wings,” they said.  “The shapes of the individual markings are consistent with the morphology of the rigid shafts of such feathers.”  The authors continually described their fossils as “primitive” as opposed to to “modern” birds.There’s no way this specimen can have anything to do with the origin of avian flight.  The authors did not even try to connect it to flight.  Feathers on this bulky dinosaur don’t help the arboreal or cursorial hypothesis.  It’s a stretch to connect it to courtship, either; the authors didn’t say if it was a male or female.  Any dinosaur so outfitted with feathers as the artwork suggests would seem to be seriously hampered from eating between courtship displays.  The authors used the power of suggestion to state, “Several roles have been proposed for primitive wings [gliding (23, 24), predatory behaviors (25, 26), or terrestrial locomotion (27, 28)], but their occurrence in a clade of ground-dwelling herbivorous (29) non-maniraptorans [the group that used to lump theropods with birds] suggests that they did not originate for predatory behaviors or aerial locomotion.” Reference 27 points to Ken Dial’s “wing assisted incline running” speculation he dreamed up by watching chukar partridge chicks (5/01/2006, 12/22/2003).  Since chukars are 100% birds, this amounts to a kind of recapitulation theory.Despite these problems, Science Now promoted the Zelenitsky paper with this overblown concoction of dogma, suggestion and composite explanation:Dinosaurs still walk—and fly—among us: We call them birds. Most paleontologists think birds descended from a group of winged dinosaurs, and thus dinos never went completely extinct. But where did the wings come from? New discoveries from Canada suggest that both wings and feathers arose earlier in dinosaur evolution than previously thought, possibly to attract members of the opposite sex or to protect hatching baby dinos.The headline was, “Dinosaurs Sprouted Wings Earlier Than Previously Thought,” even though the original paper only referred to the presence of a “pennibrachium,” defined as “a forelimb bearing long feathers that form a planar, wing-like surface but are not necessarily used in aerial locomotion.”   This definition is theory-laden since it was defined in reference to “feathered dinosaurs” (Royal Society).  Zelenitsky et al. referred to it as a “wing-like structure” but it’s basically a wrist adaptation that allows the arms of a dinosaur to fold, whether or not it was feathered.  Humans can fold their arms, too.Whatever the markings mean, therefore, they complicate the story of dinosaur-to-bird evolution.  One final observation: the specimens are found in upper Cretaceous, meaning that true birds were already flying around when it lived.  And an encore: the adult specimen exhibits the “dinosaur death pose” that indicates suffocation in water (2/16/2012, 11/23/2011).Original paper: Zelenitsky et al., “Feathered Non-Avian Dinosaurs from North America Provide Insight into Wing Origins,” Science 26 October 2012: Vol. 338 no. 6106 pp. 510-514, DOI: 10.1126/science.1225376.This shameful display of suggestive reporting in a leading scientific journal, promoted uncritically by the media, reveals the sad state of science these days.Ornithomimus was so named because of its resemblance to an ostrich.  Ostriches have feathery wings used for display and balance.  If this “dinosaur” had some kind of “filamentous feathers” (granting extremely generous license to speculation), so be it.  But evolutionists are going to need a lot better evidence than this.  More likely, the emotional mad dash to establish connections between dinosaurs and birds gives some researchers a Gold Rush mentality to strive for fame and fortune by stretching the truth.  Journal editors and science reporters are only to happy to oblige them, since another “feathered dinosaur” makes for good headlines, particularly when accompanied by wickedly overdrawn artwork (suggestion, extrapolation, visualization).Experienced readers will withhold acceptance of such wild claims, knowing full well a re-interpretation is likely, if not a retraction, after less Darwin-inebriated scientists take a look at the specimens.  Critics like Alan Feduccia and the Oregon State squad will doubtless have something to say (AIG).last_img read more

Google Mobile Web: Now With Interactive Weather

first_imgRole of Mobile App Analytics In-App Engagement Why IoT Apps are Eating Device Interfaces The Rise and Rise of Mobile Payment Technology Recently, a tweet made the rounds criticizing the iPhone weather app, imagining Steve Jobs lurking in the background, taking sadistic joy in creating entirely random weather forecasts. If you share a similar sentiment, then you’ll want to check out Google’s latest update – a nifty, localized weather feature on its mobile website.It’s nothing fancy or sophisticated, but it will quickly tell you what the weather is supposed to be like, wherever you are, at incremental times throughout the day. mike melanson What it Takes to Build a Highly Secure FinTech … “We’d been wanting to build a fun, useful, app-like way to display weather information on our search results pages in the mobile browser,” wrote user experience designer Nick Fey and software engineer Michael van Ouwerkerk. “So we pulled together a user experience designer and team of engineers and built a new weather search results snippet that lets you actually play with the results.”The solution is simple, multi-platform and just requires that you search for “weather” using Google in your mobile browser. Upon searching for “weather”, you’ll receive  a standard summary of the basic conditions, but the slider is where the neat stuff is at. As you grab and move the slider through the next 12-hour period, the sun will change to clouds or raindrops or moon depending on the forecast and the expected temperature, wind speed and humidity will change with it. Even the background will dim as the slider moves into the nighttime hours. So if you, like some others on Twitter, like to imagine that Steve Jobs is lurking in the back rooms of Apple, deviously creating imaginary forecasts to mess with your day, give Google’s new weather feature a try. If you have similar visions about now ex-Google CEO Eric Schmidt, the feature works on Android, too. Related Posts Tags:#Google#mobile#NYT#web last_img read more

221 new members for Assam Foreigners’ Tribunals

first_imgA panel of 221 members has been selected for the existing and upcoming Foreigners’ Tribunals (FTs) in Assam. Another 50 applicants have been put on the wait list.In a notification on Monday, the Gauhati High Court said the panel members comprised retired judicial officers, advocates and civil servants, who we were called for interviews from July 16 to August 11. It recommended the candidates, selected in order of merit,. The list had been prepared and published less than a fortnight before the completion of the final National Register of Citizens (NRC) on August 31.200 new tribunalsEach FT is headed by a judge-like member appointed under the FT Act, 1941, and FT Order, 1984, as per the guidelines issued by the government from time to time.Assam has 100 FTs. According to Home Department, there were initially 11 Illegal Migrant Determination Tribunals (IMDT). These were converted to FTs after the Supreme Court scrapped the Illegal Migrants (Determination by Tribunals) Act, 1983.The government established another 21 FTs in 1983. Four more were added in 2009 and the remaining 64 established in 2014 for disposal of cases that were piling up in the FTs.The government would establish 200 FTs primarily for handling cases of people to be excluded from the final NRC. These would be in addition to the existing 100 and are part of the 1,000 that the Centre had decided to help Assam set up in view of the pressure envisaged to dispose of cases of people to be left out of the NRC.Officials in the Home and Political Department said the new FTs would be distributed among six districts. Kamrup (Metropolitan) district, which covers Guwahati and outskirts, would get 67 of these, followed by Nagaon with 39, Jorhat 31, Bongaigaon 22, Sonitpur 21, and Cachar 20.“Apart from the cases of people left out of the NRC, the new FTs will also deal with the regular cases of D-voters,” a senior officer said. ‘D’ stands for doubtful or dubious voter, a category of people disenfranchised by the government for their alleged lack of proper citizenship documents.last_img read more

‘Universe Boss’ Chris Gayle wins defamation case in Australia

first_imgWest Indies batsman Chris Gayle won a defamation case against an Australian media company in the New South Wales Supreme Court on Monday over an alleged incident during the 2015 World Cup.After less than two hours of deliberation, the jury found Fairfax media had failed to establish the truth of a series of reports it ran alleging the 103-Test cricketer had exposed himself to a masseuse during the tournament.It also found Fairfax had failed to establish that the allegation Gayle had propositioned the masseuse was “substantially true”.”I came all the way from Jamaica to actually defend myself and my character as well. At the end of the day I’m very, very happy,” Gayle told reporters outside the court.”I’m a good man. I’m not guilty.”The jury also found that Fairfax, which publishes The Sydney Morning Herald and The Age newspapers, was motivated by “malice” in publishing the stories.A hearing over the amount of damages will be held at a later date but the defence lawyer for Fairfax said he would be considering an appeal, local media reported.last_img read more

Khao Lak posttsunami tourism recovery transformation

Khao Lak post tsunami tourism recovery transformationOne million arrivals are expected for Khao Lak this year, a huge transformation for the destination, following the dark days following the Asian Tsunami in 2004 according to a new report by leading hotel consultancy, C9 Hotelworks.In the year following the event hotel guest arrivals in Phang Nga Province fell sharply under 300,000 for the entire year, but in a remarkable sustained upswing the number pushed upwards to 962,020 at the end of 2015 and is expected to break the one million mark this year. View the Khao Lak Hotel Update 2016 report here: http://www.c9hotelworks.com/downloads/khao-Lak-hotel-market-update-2016-05.pdf Key drivers, according to the report, are rising Chinese and Australian visitors, adding to the European guests that still dominate the market with 80% of arrivals, resulting in a new surge of hotel development.Khao Lak’s hotel market has 104 registered accommodation units with 7,822 keys, a number which pales compared to neighbour Phuket, whose total supply is close to 50,000 rooms. But, over the past five years the destination has seen a compounded annual growth rate of 16%, a rising performance not un-noticed by both Thai and foreign hotel developers with 1,213 new rooms coming into the supply pipeline.Commenting of the market evolution C9 Hotelworks’ Managing Director Bill Barnett said: “The upward cycle in tourism is highlighted by the planned return of Bill Heinecke’s Minor Hotel Group and more international brands coming on stage such as IHG’s Holiday Inn brand. Geographically within Khao Lak we are seeing the push north for the newest and larger resorts with Bangsak in particular seeing a number of large-scale properties.” Guest Arrivals at Registered Accommodation Establishments – Phang NgaSnowbirds or winter visitors from European countries especially German-speaking nationalities have traditionally been the legacy market. These were in fact the main drivers of the destination in the period after the Tsunami. However, by 2006 foreign visitors eclipsed domestic demand for the first time and the trend has grown ever since.“Over the past few years Khao Lak has attached itself to Phuket’s fast rising airlift and China and Australia in particular, with strong arrivals in the traditionally lean summer months, driving the growth and market maturity as it becomes a year-round market as opposed to the disruptive seasonality it used to be known for,” said Mr Barnett. Data from C9’s report also points to other key emerging markets such as Japan Korea, Malaysia and Singapore as key catalysts of change.Summing up Phang Nga’s push towards the golden one million milestone Bill Barnett added: “Khao Lak has been able to attract an increasing number of visitors from nearby Phuket who have destination fatigue and are disconnected by the wide-spread urbanized of the island’s resort atmosphere. Though the destination is firmly connected to the bigger Greater Phuket infrastructure including the soon to open expanded airport, in the long-term Phang Nga will have to develop its own gateway airport in order to control its own tourism destiny.About C9 Hotelworks C9 Hotelworks is led by founder and Managing Director Bill Barnett, who brings over 30 years’ experience in the Asian hospitality and real estate sectors. Prior to founding C9 in 2003, Bill held senior executive roles in hotel operations, development and asset management.
