A beautiful model of the newly named tyrannosaurid dinosaur, Nanotyrannus lethaeus (nicknamed, "Jane"), by Meta Natural Art. 🤓🦕🦖

Happy Halloween to everyone!! 🎃 👻 🧙‍♂️🧛‍♂️🧛‍♀️🧝‍♂️🧝‍♀️🧞‍♀️🧟‍♂️🧟‍♀️🧌🦸‍♀️🦹‍♀️🦹‍♂️👽👹🧙‍♀️🧙

For those who impose and continuously say that their fantasy book is 100% true. MAGA volunteers would be greatly appreciated. 🤣

This is why I love paleontology. For over 20 years, I and most of my colleagues were skeptical about the validity of the genus Nanotyrannus. Now, say hello to Nanotyrannus lethaeus. The image below features a pack of these N. lethaeus attacking a juvenile T. rex. Art by Anthony Hutchings.

When someone tells you, "I believe every single word of the bible!" No, they don’t. They don’t believe it when it says god lies, when it says god commands child sacrifice, when it says another god defeated YHWH in battle, when it says Jesus’ followers must obey

Christian "science." For they hate true science and how it reveals that their book is a work of pure fiction.

like Giganotosaurus and Mapusaurus. It remains well debated if Aucasaurus was a pack hunter or not. If so, family groups or mating pairs could take down larger prey like medium-sized ornithopods or juvenile sauropods. Aucasaurus was possibly like its relative, Carnotaurus. It was

approximately 4.3 - 6.2 meters (14 - 20 feet) long and weighing around 700 kilograms (1,500 lbs). Its skull was short, boxy, and thick; with powerful jaws and durable teeth for tearing flesh. It had low ridges above its eyes instead of horns. Its arms were extremely reduced - with almost no fingers
