Seismosaurus
Seismosaurus was a massive plant-eater (herbivore) that lived in North America
during the
Jurassic period, between about
155 and 145 million years ago.
When initially discovered, Seismosaurus was believed
to be between 130 and 170 feet (40 to 52 meters) in length,
with most of its length was taken up by its very long neck and tail, but the body and head
being both comparatively small.
Recently however there has been discussion among scientists about Seismosaurus,
firstly about whether it should be
classified as a separate genus from
Diplodocus,
and secondly about its length - some recent estimates put its length as "only"
110 feet (33.5 meters).
Seismosaurus was a herbivore (plant-eater) that lived from 155 to 145 million years ago
