lilliput effect

mammals: nocturnal (poor color vision), small, efficient biting, chewing,
better gait for better breathing ectoterms, secondary palate

jurrasic mammals: docadonts, heremiadons, morganicadont

first dinosaur introduced: megalosaur

therians
island isolationism: lose big brain (not needed/expensive)

flowering revolution of cretacious - helped mammals who specialized in
insects

metatheria : marsupials
autheria: placentals
monotremes: split from other manmals at triassic-jurassic boundary

until disappearance, pterodactyls stemmed diversification of birds

periceactyls, ardiodactyls

there are twice as many bird species as mammal species

palecene, Global Warming, eocene

placenta was invented at least 20 times
