The mother Cayenne Teferi M Wells II and her 38 children they are the only fossils of babies from an extinct mammal relative from the early Jurassic on record credit Eva Hoffman slashed the University of Texas at Austin Albuquerque NM about 185 million years ago a hairy beagle sized animal celebrated motherhood by having 38 babies in the same clutch.

According to a new study of the skeletal remains of both mama ants the animal known as Chi ant etherium well Z wasn’t quite a mammal but rather a sign of donned a mantle relative that lived during the Jurassic period and the prodigious number of babies she had is more than twice the average litter.

Size of any mammal living today meaning that K well Z reproduced more like a reptile the researcher said Rover these babies had remarkably small uns suggesting that his mammals developed.

They traded off small ins and big litter sizes.

For larger uns and smaller litter sizes the researchers said in photos mammals through time the discovery of the mother in her 38 offspring is extraordinarily rare because these are the only known babies of a mammal precursor on.
