In Baylor County, paleontologists are assembling clues to the prehistoric world of Dimetrodon. [previously]
We think of the Stone Age as something that early humans lived through. But we are not the only species that has invented it.
While scientists have long known that modern day birds are dinosaurs (a fact that is self-evident if you ever look at a cassowary), it now appears that birds were not the dinosaurs' only attempt at flight. It may have had feathers, but the recently discovered Yi qi ("Strange Wing") had wings like a bat.
"What could you possibly have in common with a mushroom, or a dinosaur, or even a bacterium? More than you might think. In this Lab, you’ll puzzle out the evolutionary relationships linking together a spectacular array of species. Explore the tree of life and get a front row seat to what some have called the greatest show on Earth. That show is evolution." Evolution Lab is a educational game created by the Life on Earth Project and NOVA Labs
Troubles in Paradise is a review of the history and arguments of the creationism/intelligent design movement, written by James Downard.
"A remarkable international effort to map out the avian tree of life has revealed how birds evolved after the mass extinction that wiped out the dinosaurs into more than 10,000 species alive today. More than 200 scientists in 20 countries joined forces to create the evolutionary tree, which reveals how birds gained their colourful feathers, lost their teeth, and learned to sing songs." Via iO9.
A nebulous trade in forged and illegal fossils is an ever-growing headache for paleontologists. [more inside]
A gigantic fish-eater (Bigger than a T. rex!) with a crocodile snout and a large sail on its back, Spinosaurus aegyptiacus has always been a strange and enigmatic creature. It may have just become something stranger: a semiaquatic, quadrupedal theropod dinosaur. [more inside]
Scientists at Drexel university have discovered and described the most complete supermassive dinosaur ever found. According to paleontologist Kenneth Lacovara, the titanosaur "weighed as much as a dozen African elephants or more than seven T. rex. Shockingly, skeletal evidence shows that when this 65-ton specimen died, it was not yet full grown. It is by far the best example we have of any of the most giant creatures to ever walk the planet." It's name? Dreadnoughtus .
Dinosaurs were lumbering, stupid, scientifically boring beasts—until John Ostrom rewrote the book on them.
"TrowelBlazers is a celebration of women archaeologists, palaeontologists and geologists who have been doing awesome work for far longer, and in far greater numbers, than most people realize." [via]
Dimetrodon is not a dinosaur! Sorry to ruin your childhood yet again, but it's not even a reptile. It's a synapsid, which makes it one of our cousins. [more inside]
"The greatest challenge to 21st century paleontology: When commercialization of fossils threatens the science," a commentary by four paleontologists. [more inside]
Palaeocast: "An open broadcast of paleontological information, a place where the beauty, diversity and complexity of the field can be conveyed and discussed in a digital format." Every interview-centric episode is associated with a blog post, organized by era and period. [more inside]
A series of blog posts by George Washington University engineering students on the aerodynamics of pterosaur flight. [more inside]
After a species goes extinct, in some cases its "ghost" may linger in the ecosystem it leaves behind in the form of evolutionary anachronisms. [more inside]
"Dinosaurs! WTF? is a blog devoted to exposing dinosaurs for the murder oriented monstrosities they were, promoting preparations for the likelihood of their return, and outing those people who support the dinosaur agenda."
Even one of the best known dinosaurs has kept some secrets. Here is what palaeontologists most want to know about the famous tyrant.
All Your Yesterdays is a sequel to All Yesterdays: Unique and Speculative Views of Dinosaurs and Other Prehistoric Animals, by John Conway, C.M. Kosemen [deviantart] and Darren Naish. The new book is compiled from submissions to the "All Your Yesterdays Contest" (winners here) and is available as a free pdf download (although they are accepting donations).
"One thing I was wondering is if any of these paleontologists you’ve talked to have given their argument of why paleontology is important." Fossils are "just basically rocks," he said. "It's not like antiquities, where it's somebody's heritage and culture and all that."Bones of Contention: A Florida man's curious trade in Mongolian dinosaurs. [previously]
"Pretty much everyone interested in dinosaurs, in the history of life, or in such matters as the evolution of intelligence and/or brain size, will be familiar with the various speculations on ‘humanoid dinosaurs’ that have made their way into the literature." - Tetrapod Zoology on Dinosauroids [more inside]
Paleo by Jim Lawson was a comic book series set during the Late Cretaceous and featuring dinosaurs as protagonists. It was in print between 2001 and 2004, but is now being "reprinted" as a webcomic. [more inside]
"The sale of this next lot will be contingent on a satisfactory resolution of a court proceeding dealing with this matter."
On May 20th, the fossil remains of a Tarbosaurus (aka, Tyrannosaurus bataar) were sold for $1,052,500. The auction was carried out despite objections from the President of Mongolia and a court order. The problem? The remains may have been poached.

A History of Skeletal Drawings: Part 1 - pre-20th century, Part 2 - Bone Wars to the 1950's, Part 3 - Dino Renaissance to the present. Via Love in the Time of Chasmosaurs.
Darren Tanke has been guest blogging at Dave Hone's Archosaur Musings about his preparation of a Gorgosaurus (as seen here). [more inside]
"Like many paleontologists, I believe that T. rex was a hunter: a forest hunter. More specifically, I believe that T. rex used the very same hunting strategy that millions of forest hunters practice today: stand hunting from a tree."
In 1916, Bone War veteran (and poet) Charles H. Sternberg loaded 22 crates of fossils from the Alberta Badlands onto the SS Mount Temple, intending to ship them to the British Museum of Natural History. They never made it. [via Dinosaur Tracking]
"These data revealed a surprisingly consistent pattern of decomposition throughout time. This pattern shows that as these modern fish decayed, their most recently evolved features -- those characters that are most informative because they distinguish closely related animals within the same lineage -- rotted first. The last features to disappear were more ancient; those that are shared by all vertebrates, such the notochord."
Conceived at the 2007 Flugsaurier pterosaur research meeting in Munich, pterosaur.net is devoted to the titular prehistoric reptiles. [more inside]
There is no evidence that Quetzalcoatlus could see dinosaur pee with its ultraviolet vision, or that a herd of hadrosaurs could knock over a predator with their concentrated infrasound blasts.
Paleontologist Matt Wedel was a talking head in the Discovery Channel's Clash of the Dinosaurs, but was not very happy with the final product. The production company, Dangerous, responds. Finally, the Discovery Channel steps up.
"A suite of five ancient crocs, including one with teeth like boar tusks and another with a snout like a duck’s bill, have been discovered in the Sahara." [more inside]
"My cat dragged in what appeared to be an odd-looking bird. Imagine my excitement when on closer inspection, it proved to be a real live dead Rhamphorhynchus! I had to dissect it immediately! Unfortunately, my camera jammed, so I had to paint the whole process." - John Conway's Paleontography
Bone Wars is an educational game that "simulates the process of creating a scientific hypothesis and testing it against new data" (A good thing to teach kids with people like these guys running around). The game is based on the legendary Cope/Marsh feud: a conflict that caused one Dinosaur to be classified twice and could make for a really cool movie someday.
