The suberb preservation of the Shri rapax specimen: the bones forming the pelvic canal are still three-dimensionally articulated. The blue line links the thorax with the tail along both pubic and ischial canals.

La "notizia" della scoperta di impronte/resti di dinosauro in Sardegna non ha fondamento. Alcuni mesi fa, fui contattato dagli scopritori del reperto per dare una mia valutazione. Espressi scetticismo sulla natura delle "impronte". Non mi risulta ci sia uno studio scientifico su questo materiale.

Size comparison between the largest terrestrial predatory mammal (Arctotherium angustidens, Pleistocene of Argentina) and the largest non-avian theropod (Tyrannosaurus rex, Maastrichtian of USA). Arctotherium from Soibelzon and Schubert (2011), Tyrannosaurus by Hartman. #FossilFriday

Duonychus (E) and Erlikosaurus (C) are almost the same size, are from the same unit, and could barely be distinguished by just a few features of the distal humerus. I would not be surprised if future finds show they are the same taxon.

Based on humerus size, Duonychus holotype (B) is much smaller than Segnosaurus (A) and shows immaturity in vertebrae fusion. How much the fully mature form is larger than the holotype is unknown.

Duonychus is a rare opportunity to see the extent of the corneous claw in a non-pennaraptoran theropod, in this case it extends >40% the bone claw.

Today is the 80th birthday of the iconoclastic paleontologist Robert Bakker. Although not all of his hypotheses on dinosaur biology are probably valid, his contribution to the development of this branch of paleontology during the 2nd half of the XX Century is widely recognized as fundamental.

Two years ago, we published the first Mesozoic reptile from my home province. Nice articulation of a partial tail, so rare in such high-energy deposits. Our analyses supported these ichthyosaur-bearing levels about 25 My older than previously assumed. Cover by Fabio Manucci.

My first post here is a #FossilFriday dedicated to the taphonomy of Halszkaraptor, the goose-like raptor. In the CT-scan, note the sinuous shape of the vertebral column. The tail is partial (blue arrows). My concern is what happened to the missing coracoids (yellow arrow) and pubes (red arrow).
