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.

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.
