THE tallest dinosaur ever found has been dug up in Oklahoma.
With its feet flat on the ground, Sauroposeidon’s head towered 18
metres high—tall enough to look into a sixth-floor window. Rich Cifelli of
the University of Oklahoma in Norman and his colleagues announced last week that
they had found four neck vertebrae that stretch five metres.
“It’s basically a giraffe-like thing with a ridiculously long neck,” says
Cifelli. Like giraffes, the giant probably browsed on leaves from high branches.
Sauroposeidon lived about 110 million years ago, making it one of the
last of a family of massive plant-eaters that thundered across North
America.
