AboutDavid Prus Expertise I can answer any general questions about dinosaurs and on prehistoric mammals in the Cenozoic. I also know a bit about the media's various depictions of dinosaurs and their inaccuracies. I don't know much about "microfauna"-small animals, or about Paleozoic besides some knowledge about Permian animals. Plants are right out, I'm afraid.
Experience I have been interested in dinosaurs for most of my life, own a large collection of scientific papers and books on the subject, and am a member of the Field Museum in Chicago.
Education/Credentials I am in college, but studied biology and geology both in high school and as a personal effort.
Question Thank you for answering my past questions:
1)Which was the biggest carnivorous therapsid ever?? how big was it?? which were the possible prey items for it?? was it a powerful predator??
2)How heavy was Ceratosaurus ingens??
3)In your opinion which was the most formidable therapsid predator of them all??
Thank you.
Answer Big therapsids?
Eotitanosuchus at 600 kg and twenty feet long. Fed on the giant amphibian Melosaurus and the giant therapsid Estemmenosuchus
Titanophoneus and Anteosaurus at 600 kg and twenty feet long. Fed on the huge herbivore therapsids Ulemosaurus and Moschops
Inostrancevia at 17 feet long and 700 kg. Fed on the large, armored reptile Scutosaurus
It's safe to say all were powerful predators and the most terrifying creatures to roam the earth until the appearance of the archosaurs
2. The specimens of C. Ingens are only a few teeth, but they suggest an animal between 3 to 5 tons in weight
3. I would say Inostrancevia, since it had sabre teeth like a Smilodon, a completely erect posture, and probably had an advanced warm-blooded metabolism. That's like a tiger the size of a cow.
