Esperaba cousas mellores dos que se viralizaron coas proxeccións na fachada de enfrente durante o confinamento, pero vese que van a facer caixa vendendo fume. A tomar polo cu.

And cool guys from my master's thesis; Caudi- and Archaeopteryx are reproductions, but still, Las Hoyas birbs and Confuciusornis 🤩

Also neat reproductions

So the holotype of Megatherium was the first paleo mount in history and I got to see it yesterday 😁

The type material is there, but I know of workers who aren't too keen on Mateus' methodology for taxon erecting. Further back and forths are to be ecpected.

"Estimations were made in publications, but Greg Paul also had this number in his book" is far too prevalent on Wiki articles... and consistent with Greg Paul going on talk pages about why his stuff isn't more referenced.

The paper is neat, but I don't see how it relates to whether temnospondyls or lepospondyls contain lissamphibians. Or whether desmostylians are afrotherians or perissodactyls. And that's without leaving tetrapod paleo.

The juvenile dryptosaurid is STILL closer in looks to a juvenile tyrannosaurid than any of those characters, for the record. #Nanotyrannus

Ojo, que no era un animal pequeño en absoluto. Las implicaciones paleozoogeográficas son interesante, ya que los parientes de este sería el Dryptosaurus de los Apalaches, mientras que los de Tyrannosaurus, el Tarbosaurus mongol. Se encontraron en Montana yendo en direcciones opuestas.

Keep in mind, the broken clocks are at this state anyway, and aren't really getting validated. Somebody else did the work.

More dryptosaurids is a cool thing NGL.

La filogenia es bastante interesante; Bistahieversor y Jinbeisaurus como Albertosaurinos es gordo, Tyrannosaurus sigue firmemente dentro de un clado Asiático, y Nano dentro de un clado de Apalachia (que si tiene a Dryptosaurus es Dryptosauridae y no Nanotyrannidae) explica mucho

Honestly? Sister taxa and living at the same time, so may as well be a matter of opinion.
Dryptosauridae, being a 135 year old name, may be preferable to Nanotyrannidae under this topology in any case, I believe.

This is the most foolish way a paleontologist can look, for the record. Changing conclussions with new information, on the other hand? Proper science.

Deinonychus would have no issue hunting humans for food, but Utahraptor would handle a human like a leopard does with a rabbit. 500-2000 kg theropods in general would be nightmarish.

Wikipedia's loss of clarity on cladograms (which are eroded away) is quite daunting.
Canina is not a polytomy, and Urocyon doesn't form a trichotomy with Vulpini and Canini, in most analysis. If the cladogram is trying to reflect the ranked taxonomy, what the fuck.
