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.
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
Spinosaur taxonomy and evolution of craniodental features: Evidence from Brazil
A new rhynchocephalian (Reptilia: Lepidosauria) from the Late Jurassic of Solnhofen (Germany) and the origin of the marine Pleurosauridae
The Dinosaur Society T-Shirts featuring the artwork of Bob Nicholls (@paleocreations) have arrived. We're chuffed with the result - they are awesome :D.
You can buy them online on the Dinosaur Society website - we'll start sending them out next week.
If you pre-ordered, please pm or email us through the website to receive a discount code.
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.
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 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.
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.
Programme is as follows:
DISCOVERY ROOM: Full of activities for children including, fossil making, shifting sharks teeth, microfossil activities and dinosaur workshops.
Lectures in the Darwin Lecture Theatre
11.30–12.15 Dr Susannah Maidment: How to weigh a dinosaur
12.30–1.15 Professor Chris Jackson: Hot Rocks Under Our Feet: What can we learn about Volcanism from X-raying Earth?
2.00–2.15 Presentation to the Winners of the Photographic Competition by the GA President. Entries on display all day in the Haldane Room.
2.15–2.00 Professor Iain Stewart: Hot Rocks: The Fall and Rise of UK Geothermal Energy
3.15–4.00 Professor Lidunka Vocadlo Core! What a scorcher! Hot and squashed in the centre of the Earth

The Dinosaur Society will be at the GA Festival of Geology, Saturday the 4th of November. The venue is UCL, Gower Street, London. Come along to enjoy all the geological treats on offer and meet some of the society organisers. We'll hopefully have our new T-shirts for sale as well as certificates for any new members.
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.
Interesting read including a story on pg 11 entitled "Skye's Extraordinary Dinosaur Discoveries".
