Here's a quick roundup of the science articles, published papers, and recent news that I have found interesting. Enjoy!

Scientists Uncover Yet Another Reason to Protect Bears Ears Monument - A major Triassic-age fossil discovery in Bears Ears National Monument serves as another reminder that the monument must be protected from scaling back and commercial redevelopment.

Locomotion of bipedal dinosaurs might be predicted from that of ground-running birds - Story regarding a Feb. 21 paper published on Plos One that correlates the movement of bipedal non-avian dinosaurs with those of modern birds in an attempt to better understand the former. Paper written by Peter Bishop from the Queensland Museum, Australia.

A nestling-sized skeleton of Edmontosaurus (Ornithischia, Hadrosauridae) from the Hell Creek Formation of northeastern Montana, U.S.A., with an analysis of ontogenetic limb allometry - From the Journal of Vertebrate Paleontology, written by Matuesz Wosik, et al. Excerpt: The Hell Creek Formation preserves one of the most intensely studied late Cretaceous terrestrial fossil units. Over 22 dinosaur genera are currently recognized from this unit, but the record of juvenile individuals is surprisingly limited. Here, we document a nestling hadrosaur that represents the first occurrence of an articulated nestling dinosaur skeleton from the latest Cretaceous (late Maastrichtian) of North America.

The new specimen forcing a radical rethink of Archaeopteryx - Only the 12 specimen of Archaeopteryx was described in February, after being discovered in 2010. The specimen is adding a lot to our knowledge of this relatively rare genus, and making as many waves for disproving things we thought we already knew. It's also an interesting situation where a privately owned fossil specimen has been studied carefully enough to publish.

Flipside of a dinosaur mystery: 'Bloat-and-float' explains belly-up ankylosaur fossils -  Dr. Jordan Mallon of the Canadian Museum of Science studied 32 different ankylosaur fossils in an attempt to explain why they are primarily found upside down. Collaborating with experts in the field of modern animals like armadillos, Mallon presents his findings. Article also contains a link to his paper in the online journal Palaeogeography, Palaeoclimatology, Palaeoecology.
