Question
Hi did giganotosaurus live alongside mapusaurus and tyrannotitan?
if they did who would be the apex predator? thanks
Giganotosaurus-98 mya, Candeleros Formation
Mapusaurus-96 mya, Huincul Formation
Tyrannotitan-115 mya, Cerro Barcino Formation
If they were different genera, they were not contemporary. It's still possible that they are the same genus or sister species.
It is very unlikely there was overlap between these carnivore species. If there was, Giganotosaurus was a head larger than the rest and might have been top predator
I hope this helps

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. Please do not ask me to identify fossils.
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.
