brontosaurus

most famous of the dinosaurs
greco name means thunder lizard
a herbivore grazing planes
digestion aided by a gizzard

you may have traveled once in herds
nomadic clans of the jurasic
enormous tails swung in defense
gentle giant dino classic

in movies longneck Little Foot
you set our saurus loving hearts aglow
Transformers' Sludge the Dinobot
and in song by ELO

originally a fabrication
by Othniel Marsh in presumptuous haste
a borrowed skull from Camarasaurus
to lead the paleontologist's race

some say you're really Aptosaurus
and these men of science may ignore us
but your fans will express in chourus
to us you're allways Brontosaurus
