Question

What mammals were present on the time of the Dinosaurs?

Answer 1

Some Mesozoic mammals include:

Morganucodon - a shrew-like mammal recorded in Wales

Megazostrodon - another shrew-like mammal from South Africa

Sinoconodon - from China



Adelobasileus, a synapsid from Texas, is older but the remains are fragmentary and perhaps it's not a mammal.

Answer 2

Actually, there were small rodent sized mammals present during the Mesozoic Era (age of dinosaurs). However, they were significantly "outcompeted" by dinosaurs which kept their evolutionary advancement in check. I have heard that there has been a recent discovery of a beaver-type mammal that existed during the Triassic Period, but I have not been able to find a resource to confirm this.

Answer 3

Here's a link to a news item about what is now the largest known mammal of that time:
