Pachycephalosaurus
Click here for more Pachycephalosaurus Pictures
Pachycephalosaurus was a herbivore (plant-eating) dinosaur that
lived during the late Cretaceous period,
about 76 to 65 million years ago,
in North America.
It was one of the dinosaurs that died out in the Cretaceous-Tertiary
extinction,
65 million years ago.
The name Pachycephalosaurus means "thick-headed lizard",
and describes the creature's most noteworthy feature:
the huge 10 inch (25 centimeter) thick
bone dome on its head. At the rear of the dome were a number of bony knobs,
and the animal's snout also possessed several short bony spikes.
This has led most scientists to conclude that the animal was probably
related to the
Ceratopsians
(which include
Protoceratops,
Psittacosaurus,
Styracosaurus
and
Triceratops),
although unlike most
Ceratopsians,
Pachycephalosaurus is believed to have been bipedal.
It was once thought that Pachycephalosaurus would have used the dome
on its head either to engage in butting contests for mates (similar to
modern big-horned sheep), or to defend against predators. However,
it is now believed that this could not have been the case:
the head bones do not appear to be strong enough for such impacts,
the skulls lack shock absorbing features, and there no evidence of
scars or other damage have been found on
fossilized
Pachycephalosaurus skulls.
Another somewhat unusual feature of Pachycephalosaurus is its teeth.
The animal had very small ridged teeth which would have been
far less capable of chewing tough, fibrous plant material than
other herbivorous dinosaurs of the late Cretaceous. It is therefore
thought that perhaps Pachycephalosaurus lived on a diet of
leaves, seeds, fruit and perhaps insects.
So far, only the skull of Pachycephalosaurus has been discovered.
Scientists estimate that the fully grown creature was 15 feet (4.6 meters) long,
and weighed about 950 pounds (430 kilograms).
They have come up with these figures by examining
the skull and extrapolating the likely size on the creature based on
the head-to-body ratios of its close relatives.
