Ankylosaur Dinosaurs
The Ankylosauria (meaning "fused lizards") dinosaurs
were a infraorder of the the
Ornithischian
dinosaurs.
Together with the
Stegosaurs,
Ankylosaurs form the Thyreophora ("shield bearers") suborder
of Ornithischia.
Dinosaurs in the
Ankylosauria infraorder include
Ankylosaurus
(of course!),
as well as,
among others,
Animantarx,
Edmontonia,
Euoplocephalus
(sometimes known as "Scolosaurus"),
Gastonia, and
Tarchia.
Ankylosaurs first appeared during the early
Jurassic period,
and survived until the
end of the
Cretaceous period,
about 65 million years ago, when all the remaining non-avian
dinosaurs became
extinct.
All Ankylosaurs were herbivores (plant-eaters),
quadrupedal (walking on four legs),
and protected by armor. Although the amount of armor
did differ between species. The Ankylosaurs are principally divided into
two families - the Ankylosauridae and the Nodosauridae -
the big difference between that most (but not all) of the former have
bony clubs in their tails, whereas none of the latter family where equipped
with such clubs. Recent research has however added one additional family,
Scelidosauridae to the Ankylosaurs - this group currently
contains only two early and primitive armored dinosaurs:
Bienosaurus and Scelidosaurus.
Ankylosaurs first appeared during the early Jurassic, about 200 million years ago, and survived until the end of the Cretaceous period, about 65 million years ago
