In evolution there is no thin line where mammals all of sudden exist. Rather characteristics accumulate until the creature is marginally more mammal than anything else.The first mammals appeared in theLate Triassic
epoch (about 210 million years ago) . Even then they were monotremes like the platypus which laid eggs and did not nurse their young, unlike mostmost modern placental mammals.
