Another significant character that distinguishes sauropod
groups is the presence/absence and the morphology of the manus digit I claw mark (pollex).
It turns out the prints found in 2009 are part of a 110-step trackway that extends over 155 m - a world record for sauropods
, which were the largest of the dinosaurs.
The presence of an anteroposteriorly short neural arch seems to exclude this caudal vertebra from Theropoda, and its general morphology more closely resembles that of sauropod
middle and posterior caudal vertebrae.
dinosaurs, which the study said included the largest terrestrial animals to have ever evolved, dates back to 66 to 84 million years ago in present-day Argentina during the Upper Cretaceous age.
are the ones that have long necks and tails but quite small brains.
Until more bones are discovered the team have simply nicknamed Britain's oldest sauropod
dinosaur Alan, after the finder of this prehistoric giant, Alan Gurr.
Preliminary estimates are that this creature, a species of sauropod
known as a Titanosaur, would have stood some 130 feet in length and weighed in at 77 tons -- the weight of 14 fully grown elephants.
The palaeontologists say the find is thought to be a new species of titanosaur - a huge herbivore of the long-necked sauropod
group that lived in the Late Cretaceous period.
Paleobiologist Paul Upchurch at University College London, a sauropod
expert who was not involved in the study, said the fossils suggested not all diplodocids were killed at the end of the Jurassic period around 140 million years ago.
The creature is believed to be a new species of Titanosaur, a long-necked, long-tailed sauropod
that walked on four legs and lived some 95 million years ago in the Cretaceous Period.
Pablo Gallina, a researcher at Buenos Aires' Maimonides University, described the find as the first definitive evidence that diplodocids reached South America, and the most recent geologic record of this branch of sauropod
With Emr yet to announce details of the dinosaur it has bought, it can only be assumed that the "giant lizard" to be on display is perhaps a sauropod
-- a herbivore with a long neck and tail, small head, and massive limbs.
There are several Indian dinosaur specimens that are currently missing including both small and large specimens of sauropod
and theropod dinosaurs," the researchers said.
A simple mathematical model suggests that the microbes living in sauropod
dinosaurs may have produced enough methane to have an important effect on the Mesozoic climate" 150 million years ago, Dave Wilkinson of Liverpool John Moores University said.
Like gigantic, long-necked, prehistoric cows, sauropod
dinosaurs roamed widely around the Earth 150 million years ago, scientists reported in the journal Current Biology on Monday.
