The nodosaurid dinosaur, Glyptodontopelta is mostly known from isolated osteoderms ("armor plates"). The specimen SMP VP-1580 (State Museum of Pennysylvania) is however, the most complete known specimen, comprising parts of the skull, hundreds of osteoderms and fragments. This specimen was discovered in 2003 by Warwick Fowler, in the Naashoibito Member of the Ojo Alamo Formation (Maatrichtian, Late Cretaceous) of the San Juan Basin, New Mexico, during an expedition led by Dr. Robert Sullivan.

The official postcard (of the American Museum of Natural History) says this is a Barosaurus, and that "this unique freestanding mount is the only Barosaurus on view in the world". This was true until the installation of another Barosaurus specimen at the Royal Ontario Museum. The adult specimen pictured is AMNH 6341, classified as Barosaurus lentus. The juvenile specimen (AMNH 7530), originally classified as a juvenile Barosaurus, has since been reclassified as a specimen of Kaatedocus siberi.

Otozoum tracks in the Dinosaur State Park and Arboretum, Rocky Hill, Connecticut, USA. The exhibit sign reads: "These large negative tracks were made by a heavy animal that walked on four toes and had a short stride. It may have been a prosauropod. All of these tracks have rare skin impressions. This specimen was removed from the Portland Quarry in 1896. Donated by Wesleyan University."

Morphological variation in the Deltapodus ibericus holotype trackway from the CT-1 tracksite. (a) False-color depth maps and interpretative outline drawings of a selection of manus–pes sets within the trackway. Note the variation in manus (from crescent, kidney to semicircular shapes) and pes (reversed delta, semirectangular, and oval shapes) tracks depending on the manus–pes set. Note also that some manus are overprinted by the pes. (b) Mediotype of the pes impressions based on 4 specimens with a mean footprint length of 0.48 m. Note that the morphology of the posterior part of the print is slightly biased (more quadrangular) because this area in track 1CA17p is broken. (c) Mediotype of the manus impressions based on 2 specimens with a mean footprint width of 0.37 m. (d–f) Pictures of a selection of the best-preserved tracks (manus–pes set 1CA23, pes 1CA17p and manus 1CA3m). The false color depth maps were generated with the software CloudCompare (https://www.cloudcompare.org/) and the mediotypes with the software DigTrace (https://www.digtrace.co.uk/).

Ancient long snouted croc from Egypt rewrites evolution
hunting predator Egypt fossil specimen discovery evolution
A newly identified crocodile relative from Egypt pushes back the origins of the marine-hunting dyrosaurids by millions of years. The fossil, Wadisuchus kassabi, shows a mix of primitive and advanced traits that mark a key evolutionary transition. Rare specimens of different ages reveal how these ancient predators developed. The find reinforces Africa as the center of early dyrosaurid evolution.

Mongolia Cretaceous Early Cretaceous specimen Dinosauria Pachycephalosauria Zavacephale
 This week we'll be looking at a newly described little dinosaur that greatly expands our knowledge on one of the most unusual kinds of dinosaurs, the pachycephalosaurs.  Welcome Zavacephale rinpoche!Zavacephale lived in what is now Mongolia during the early Cretaceous period, between 119 and 110 million years ago.  From snout to tail the specimen found would have only been about three feet (1 meter) in length, but it likely would have been able to grow larger.  The genus name, Zavacephale, tran

New fossils reveal a hidden branch in human evolution
tooth Ethiopia fossil specimen discovery evolution
Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with multiple species coexisting. Newly discovered teeth reveal a previously unknown species of Australopithecus that lived alongside some of the earliest Homo specimens nearly 2.8 million years ago. This suggests that nature tested multiple versions of “being human” before our lineage endured.
