For #fossilfriday the weird extra osteoderms in the second cervical ring of _Edmontonia_ AMNH 5665. These extra osteoderms nearly close the ring ventrally and are unique to this specimen among ankylosaurs. The specimen can be viewed in 3d here t.co/ORvOrpCTIE

A daily reminder that significant specimens are constantly being illegally trafficked. Right now, on eBay and various auction sites, one can find Chinese paravians and psittacosaurs, Burmese paravians, teeth and bones from Niger, and-in this instance-part of a Spicomellus

For #FossilFriday a panoply of the basal #ankylosaurid Liaoningosaurus, known by literally dozens of juvenile specimens. The largest specimens are around 50 cm #thyreophora #ornithischia

Since it's #haolong day and #fossilfriday here's some #iguanodontian specimens from Liaoning, spanning from 40 cm to over 8 m, many preserved with soft tissue.

Skull roof elements of Tuojiangosaurus. The supraorbital (n.6)show and interesting pattern of conspicuous tubercles. While stegosaurs have often ornamentations in the shape of grooves and pits the supraorbital of T. vaguely recall the caputegulae of ankylosaurs #thyreophora

I have potential information about the whereabouts of the stolen material from your site, can I send you a PM?

Leaving this here for no particular reason... #spinosaurus #theropoda

Here's the partial mandible of Tylocephale for further reference

Moreover, it's likely Prenocephale sports a dentary fang. Maryanska noted the arched premaxillary diastema similar to heterodontosaurids, and was later corroborated by the discovery of Goyocephale. Here's a Nemegt pachy's jaw for reference

So, we have a late Cretaceous Lagerstätte...in Africa!? Finger crossed for further development www.palaeosa.org/uploads/4/5/...

it's on par with the Seckenberg Psittacosaurus in term of soft tissue preservation...

What has a "thagomizer", extensive skin impression, and a massive lower jaw? #stegosauria #ornithischia source m.sohu.com/a/730240896_...

Another one from the other account. Holotype of Pinacosaurus mephistocephalus. Love how the forelimbs are still articulated and tucked under the body. #Thyreophora #ornithischia

Who doesn't like the complete skull of a basal #hadrosauroid? Here's Xuwulong, from the Early Cretaceous of China #fossilfriday #ornithischia source: Nimrf.net.cn

Reposting stuff from my other account. A chubby Liaoningosaurus with a exquisitely preserved skull. It's unclear if the mass around the orbit is a sclerotic ring or part of the unfused prefrontale/supraorbitals...of note also the pointed premaxillae #thyreophora #ornithischia

Food for thought... Kentrosaurus distal spines from Mallison 2011, Dacentrurine indet. From Company et al 2010

A monograph would be SO welcome...if there is a taxon that could link heterodontosaurs and pachycephalosaurs that's Tianyulong

There are at least 6 undescribed skeletons of various degree of completeness. One of these was used to create this sculpture by Jason Brougham. David Hone mentioned in a podcast about another one which have a mohawk through all the tail. Individuale variation? Thanks for the advertising 😁
