Sauropod Dinosaurs
The Sauropoda (meaning "lizard-footed") dinosaurs
were a infraorder of the the
Saurischian.
Together with the infraorder
Prosauropods,
they form the Sauropodomorpha) suborder of
Saurischia.
Dinosaurs in the Sauropod infrarder include, among others,
Apatosaurus
(also known as "Brontosaurus"),
Brachiosaurus, and
Diplodocus.
Sauropods first appeared during the later part of
Triassic period,
and at that time resembled their sister infraorder, the
Prosauropods.
By the late
Jurassic period,
Sauropods had become extremely widespread, and they survived until
the end of the
Cretaceous period,
about 65 million years ago.
Of course during all this time, no single species survived - instead a succession
of different Sauropod lineages appeared at different times.
At the end of
Cretaceous,
the Sauropods finally became
extinct,
along with all the other non-avian dinosaurs.
Sauropod dinosaurs were herbivorous (plant-eating). They were quadrupedal
(walking on four legs), and they had thick pillar-like legs with five
toes, although only three toes had claws.
They had
long necks and small heads and usually had long tails..
Additionally, some Sauropods had armor such
bony osteoderms
(found for example in
Ampelosaurus
and
Saltasaurus),
clubs in their tails
(for example in Shunosaurus),
or spined-backs (for example in Augustinia).
Sauropods are of course well-known for being large animals.
Even the smallest dwarf species of Sauropod were 20 feet (6 meters) long,
and the largest Sauropods were at least 130 feet (40 meters) long.
There is evidence that there may have been some species that
grew to 180 to 200 feet (55 to 60 meters)
in length.
Why Sauropods evolved to become so large remains a matter of debate.
Clearly there was some evolutionary advantage to being such huge
sizes, but we can not entirely sure what it is.
Some hypotheses that have been proposed include
the relative immunity from predators that large size conveys,
longer life spans,
greater energy efficiency,
or simply the fact that large-size allows
herbivores to digest food more effectively.
There is a good evidence (for example
fossilized
trackways) that many species of Sauropods lived in herds. It is thought
that many herds were separated by age, as juvenile animals appear to
have eaten a different
diet from adults.
Sauropods first appeared during the early Jurassic period, and survived until the end of the Cretaceous period, about 65 million years ago
