Redescription of Arundel formation Ornithomimosaur material and a reinterpretation of Nedcolbertia justinhofmanni as an “Ostrich Dinosaur”: Biogeographic implications

I honestly think this paper needs a lot of work to be a valuable addition to our knowledge. Perhaps most troubling is the lack of any real redescription, which is the title of...

Theropod specimens from the Navesink Formation and their implications for the Diversity and Biogeography of Ornithomimosaurs and Tyrannosauroids on Appalachia

Hi again Chase. I recently discovered that Yun (2017) copied some of my commentary on macropus from The Theropod Database without attribution in his paper- http://theropoddatabase...

The neck of Barosaurus was not only longer but also wider than those of Diplodocus and other diplodocines

Abstract- "It is related to the sympatric Diplodocus". Isn't every organism? Well, that lived at the same time as Diplodocus anyway. Pg9-10- The comparison to brachiosaurs see...

The taxonomy of a new parvicursorine alvarezsauroid specimen IVPP V20341 (Dinosauria: Theropoda) from the Upper Cretaceous Wulansuhai Formation of Bayan Mandahu, Inner Mongolia, China

I noticed table B wrongly says "Vertebral element" instead of Appendicular element, Pedal element, etc.. In Table B, a right MTIII is listed instead of whatever phalangeal fragmen...

The blue-green eggs of dinosaurs: How fossil metabolites provide insights into the evolution of bird reproduction

I'd only like to note that the referral of any or all Macroolithus yaotunensis to Heyuannia has no published support. Cheng et al. (2008) referred their eggs to "Heyuannia huangi...

Insight on the anatomy, systematic relationships, and age of the Early Cretaceous ankylopollexian dinosaur Dakotadon lakotaensis

While I like the anatomical section, the phylogenetic section has a major issue that renders its results suspect. The authors state "we did not proceed to calculate a maximum agre...

Comparative digestive physiology of archosaurs with notes on bird origins

First, I should note this manuscript is a perfect example of what Makovicky and Dyke (2001) critiqued in their paper "Naive falsification and the origin of birds", where a single s...

Comparative digestive physiology of archosaurs with notes on bird origins

Now that you have the revised version up, I'll tell you no one familiar with dinosaurs is going to believe your claims that Psittacosaurus just happens to preserve consistent gastr...

Hypothesis: Avian flight originated in arboreal archosaurs gliding on membranous wings

"The body of theropods was covered mostly by typical reptilian scales" is also untrue considering _Sciurumimus_, compsognathids, ornithomimids, _Dilong_, _Yutyrannus_, etc., even g...
