"...these animals had brains of typical lower vertebrate
size...since their endocasts were all very near the volume of these
expected brain sizes and since the endocasts present maximum limits on
their brain sizes, the mammal-like reptiles, in short, were reptilian
and not mammalian with repect to the evolution of their brains...There
are few suggestions of mammalian features in the brains of the
mammal-like reptiles...The forebrain, to the extent that its position
is identifiable, was of reptilian size and shape. This was not the
case the the earliest known fossil mammal...The earliest mammal for
which there is reasonable evidence, Triconodon of the Upper Jurassic
period, was apparently already at or near the level of living
'primitive' mammals such as the insectivores of the Virginia opposum.
It was certainly lager brained than its reptilian ancestors of
comparable size." (Evolution of the Brain and Intelligence)
