Latest Dinosaur News

Up to the minute dinosaur news articles.

Some articles relevant to the group courtesy of PLOS Paleontology Community:

Xenoposeidon is the earliest known rebbachisaurid sauropod dinosaur: Represented by a single partial dorsal vertebra, this fossil is still sufficiently unique to represent the earliest known rebbachisaurid by some 10 million years. Electronic 3D models were invaluable in the study.

Stable Isotopes Reveal Rapid Enamel Elongation (Amelogenesis) Rates for the Early Cretaceous Iguanodontian Dinosaur Lanzhousaurus magnidens: The study suggests rapid amelogenesis evolved among iguanodontians that was later exapted for the evolution of the hadrosaurian feeding mechanism. The subject of the study, a fossil from China has the largest known herbivorous dinosaur teeth.

Site of asteroid impact changed the history of life on Earth: the low probability of mass extinction: This study postulates that the location of the Chixulub impact was crucial to the subsequent extinctions. The high carbon and sulphur content in the sediments involved is relatively rare in global terms therefore the effects would have been much reduced if the impact had occured elsewhere.

Article

Several open source articles related to dinosaurs and vertebrate paleontology have been published this week including:

The Evolution of Ornithischian Quadrupedality: Ornithischian dinosaurs were primitively bipedal, but reverted to quadrupedality on at least three occasions. Postulated causes include Increased head size influencing the position of the centre of mass. Its also possible that the evolution of herbivory played a role.

The evolution of the manus of early theropod dinosaurs is characterized by high inter- and intraspecific variation: The origin of the avian hand, with its reduced and fused carpals and digits from the complex wrists of early dinosaurs represents one of the major transformations of manus morphology among tetrapods. This paper looks at the early stages of this evolution, the five- to four-fingered transition among early dinosaurs

Red T-Shirt featuring Velociraptor - Adult size small

Bob Nicholls' lovely artwork featuring Sinosauropteryx prima in its newly postulated favoured habitat of the open plain (feeding on a lizard as discovered in the belly of one of the fossils used in the study) is featured on the latest front cover of Current Biology.

The paper entitled "Reconstruction of Sinosauropteryx prima from the Jehol Biota" examines the remarkable preservation of pigmentation within the proto-feathers of fossil specimens allowing for the recognition of striping on the tail and countershading, as well as a “bandit mask” band of pigmented feathers along the eye.

The sharp distinction in the countershading is taken as evidence of a palaeoenvironment in the open sun, rather than in shaded forest as previously thought.

Smithwick et al. reconstruct the coloration of the small carnivorous dinosaur Sinosauropteryx. It had a bandit mask and striped tail and was also countershaded (dark on top, light below). Using 3D models under different light, the authors show that its camouflage would have worked best in an open ha...

A new pterosaur found by members of the Mongolian Academy of Sciences had a 32-foot wingspan and likely feasted on baby dinosaurs.

The partial fossil was found in the western Gobi Desert, as detailed in The Journal of Vertbrate Technology.

The find may prove to be larger than Quetzalcoatlus, found in Texas in the 1970s, and Hatzegopteryx, found in Romania in the 1990s, both with estimated wingspans of 32 to 36 feet and about as tall as a large giraffe.

Originally discovered in 2006, the fossil fragments were so broken that they took years of work to interpret.

A new pterosaur found in Mongolia had a 32-foot wingspan and likely feasted on baby dinosaurs.

A remarkable new Dinosaur fossil possibly the size of a T-Rex has been found on the Isle of Skye by scientist from the University of Edinburgh and the National Museum of Scotland. This follows another recent discovery on the Isle of Eigg.

Palaeontologist Elsa Panciroli said that previous discoveries in Scotland had mostly amounted to some individual bones and tracks but they had now uncovered something much bigger which is currently undergoing investigation.

This follows the discovery 2 years ago of numerous large sauropod and smaller possibly theropod footprints, also on Skye.

Full details of both the Skye and Eigg fossil discoveries have yet to be released due to funding stipulations but the news is expected to be published in National Geographic in the future.

This is an awesome video of the fun to be had as a vertebrate palaeontologist - features scientists at the Burke Museum gradually revealing the exquisitely preserved teeth of a T-Rex skull found in the Hell Creek formation, Montana.

T. rex teeth emerge from the "Tufts-Love" T. rex skull in this Facebook Live video. More of the T. rex is uncovered every day!

The Dinosaur Society added 5 new photos.

Just a reminder that The Dinosaur Society will be attending the Geologists Association Festival of Geology tomorrow at UCL, London. Unfortunately our T-shirt printers have not yet completed our order so we will not have any for sale on the day.

However, we will be selling exclusive prints of works by the artists who exhibited at Dinosaurs at Barnes last year. One of those was Bob Nicholls who will be attending, running several Dino art activities/workshops through the day.

The weekend will be full of fun so come along and take a look if you are in town.

The Dinosaur Society shared Peter Foxík Agricola's post.
Recent episode of BBC radio pgoram "In Our Time" looks at feathered dinosaurs, guests are Michael Benton, Steve Brusatte, and Maria McNamara

Another study using the reconstruction of the shading of dinosaurs to infer some features of the palaeoenvironment, in this case the diminutive theropod dinosaur Sinosauropteryx.

Based on analysis of 3 of the best preserved specimens and 3D modelling of potential shading patterns, the researchers postulate that they lived in more open habitats rather than close forests as originally thought.
