Rare Mammal Fossil Found with Babies

Kayentatherium bore more than twice the average litter size of any living mammal – numbers akin to reptilian reproduction. Researchers think the babies were probably developing inside eggs or had just recently hatched when they died during the Early Jurassic period. This is among the best evidence that a key development in the evolution of mammals was trading brood power for brain power. Eva Hoffman, formerly of the University of Texas, now at Harvard told us more.
