About David 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.

Paleontology (Dinosaurs) - who's closer to birds??


Expert: David Prus - 7/4/2009

Question
Thank you for answering all my questions:
1)Can you put these families of dinosaurs from the less bird-like to the most bird-like??
Allosauridae
Spinosauridae
Abelisauridae
Coelophysidae
Ceratosauridae
Megalosauridae
Tyrannosauridae
2)If they ever meet, who'll be dominant, Saurophaganax or Torvosaurus??
3)What led scientist to classify Abelisaurids as quite close relatives of Ceratosaurids??
4)Can you put these animals from the less powerful to the most powerful:
Titanoboa
Epanterias
Abelisaurus
Carnotaurus
Anteosaurus
Postosuchus
Afrovenator
Gojirasaurus
Ivantosaurus
Fasolasuchus
Saurophaganax
Dilophosaurus
Herrerasaurus
Majungasaurus
5)What would happen if Gojirasaurus was introduced in Brazil??

Thank you.

Answer
1) Coelophysidae
Abelisauridae
Ceratosauridae
Megalosauridae
Spinosauridae
Allosauridae
Tyrannnosauridae

2) Saurophagnax's size would make it dominant. They shared the same habitat and may have hunted different prey

3)Both groups had large, boxy heads, gracile jaws, small arms, and small brains.

4) Herrerasaurus
Gojirasaurus
Anteosaurus
Dilophosaurus
Postosuchus
Ivantosaurus
Titanoboa
Fasolasuchus
Majungasaurus
Carnotaurus
Abelisaurus
Afrovenator
Epanterias
Saurophagnax

5) A new top predator emerges, but it would have the same problems as Megalania-too much human pressure, not enough big game

I hope this helps
