Daily Dino Fact: More dinos than you’d think
Q: Do scientists have about an estimated amount of how many dinosaurs there were? -Flyergal
A: The only information we can truly know about how many dinosaurs there were is what we collect from fossils. Obviously, we haven’t recovered every single dinosaur that existed and our numbers are less than what actually lived. In a report released in 1990, Peter Dodson from the University of Pennsylvania estimates there were between 900-1200 genera of dinosaur present on earth during the course of the Mesozoic.
Even he admits that the number is probably smaller than the actual number, but it’s the best estimate we can give based on current data. Currently we’ve collected over 500 genera of dinosaur in addition to 100 genera (called nomen dubium) that may or may not be unique dinosaurs. There are over 100 genera of dinosaur right now waiting approval by the International Committee on Zoological Nomenclature.

What if just when a adult gives birth then a predator comes what will the adult do if the adult is weaker ( lets say the predator is a spinosaurus and the adult is a brachiosaurus)?
