Da oggi "Il Dilemma dei Dinosauri" è disponibile nelle librerie e negli store online: www.bollatiboringhieri.it/libri/andrea...

Glad to introduce a new fish-eating Cretaceous bird, Kunpengornis anhuimusei, which I coauthored with Xuri Wang and colleagues.

The world deserves a dromaeosaurid cartoon from the Djadokhtan time.

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.

My new theropod species and paper (link at end of post) theropoda.blogspot.com/2025/07/move...

The first feathered theropod I co-authored is now 12 years old. And the future? I have cute specimens under study :-) theropoda.blogspot.com/2013/05/auro...

My new paper about the giant theropods from the mid-Cretaceous of North Africa. We provide evidence that Deltadromeus is an immature morph of Bahariasaurus and that Eocarcharia is a spinosaurid-allosauroid chimaera. www.italianjournalofgeosciences.it/297/article-...

My vote during the Conclave goes to Luis Tagle.

JD Vance is for the catholics what Liz Truss was for the anglicans.

We will forever remember Pope Francis as the guy who trolled US VicePresident with Italian chocolate eggs.

JD Vance is such a bad catholic that the Pope himself died after meeting him...

Female Silver Surfer Everyone: damn woke! Me: so sexy lady!

An enigmatic digging theropod? I am skeptical: theropoda.blogspot.com/2025/04/un-e...

Was 2005 the best year since the end of the Cold War?

Make Umbrella Great Again.

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.

1 of 2: We live in a world where scientists are pushed to publish in high impact journals in order to survive in the academic system. Many scientists would sell their mothers in order to have their name in a Nature or Science paper... BUT...

The Colossal guys introduced in my FB page their arbitrary definition of species.

The fake direwolf is the Musk method applied to biology.

It's the movie of the year.

Science, not BS.

You grow up when you realize that you and your particular problems are not the center of the universe. Social media somewhat have been delaying this maturation process, at a pandemic scale.

Dinosaur science is a more complex than most think.

Over 100 tooth marks on a sauropod bone, referred to theropod, notosuchian and perhaps mammal scavengers.

A discussion on the illusion of "anatomical accuracy" in paleontology (in Italian, but with a [not always perfect] language translator button on top of page).

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

My new post about the problematic status of the Bayanshiree Formation therizinosaurids (including Duonychus) theropoda.blogspot.com/2025/03/duon...

A possible large-reptile lineage surviving the K-Pg extinction, or, alternatively, one which quickly evolved large size just after the extinction.

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.

Therizinosauridae added to the list of theropod lineages reducing the 3rd finger to a vestige.

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.

Il mio ultimo libro, se siete interessati alla biologia dei dinosauri.

Our Social Security and schools are in good hands!

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).
