Seismosaurus
size-muh-SAWR-us
Seismosaurus was an enormous, long-necked, whip-tailed,
small-headed dinosaur. It measured about 130-170 feet long and
was roughly 18 feet tall (measured from the ground to the top
of the shoulder). may have weighed about 60,000
pounds. It was among the longest land animals that ever lived.
Seismosaurus' nostrils were at the top of its tiny head. Its small mouth
had peg-like teeth, but only in the front of the jaws. Its front legs
were shorter than its back legs, and all had elephant-like, five-toed
feet. Its short legs may have helped stabilize this enormous dinosaur.
One toe on each foot had a thumb claw, probably for protection. Its
backbone had extra bones underneath it, which had bony protrusions
running both forwards and backwards (chevron shaped), probably for
support and extra mobility of its neck and tail.
Seismosaurus was an herbivore (it ate only plants).
Seismosaurus was a sauropod, whose intelligence was the among the
lowest of the dinosaurs.
True or False? Seismosaurus was an ancient ancestor of the seismograph?
That is False because a seismograph is an instrument used for measuring the motion of the ground!
