Artist's Description

Final for Triceratops horridus, a Late Cretaceous (68 – 66 million years ago) herbivore, the first of the horned ceratopsian dinosaurs to be discovered. It’s remains were originally found by Othniel Charles Marsh, in the spring of 1887. though he thought that the fossil cores that fit the animal’s brow belonged to a species of extinct Pliocene Bison. It wasn’t until 1889 that he realized his error and named the species Triceratops, meaning “Three Horned Face.”

Marsh’s discovery became the most well known genus of the Ceratopsidae family, a large and varied group known mostly for the brilliant horn and frill displays they possessed. While the facial protrusions of Triceratops and it’s kin look to be purely for defense, many of theorized that the wide variety of horn and frill combinations might be mostly for display, either for attracting mates, or perhaps species and gender identification.

As of 2010 and 2011 several specimens of ceratopsians previously thought to have been representatives of other species, such as the larger Torosaurus, have now been theorized to actually have been just stages in growth of Triceratops itself, this research is based on comparison of 28 difference specimens that were confirmed to be Triceratops, 10 of which could be positively placed in order of a growth series, showing a pattern of growth and changed, particularly in the frill shape, size, and horn shape. Younger specimens show smaller horns with the brow horns curved backwards and a smaller pushed back frill, lined with individual triangular spikes. As the animal grew, the frill became broader, the frill spikes fused to the rest of the skull and became more rounded, and the brow horns grew longer and moved into a forward facing position. This theory is still being debated as it applies to Triceratops and several other species of dinosaurs, more specimens need to be analyzed to determine if this is true.

A fully grown Triceratops measured around 30 feet in length, weighing in at roughly 5.5 tons, It’s head made up around 5 feet of it’s total length with 3 feet of horns attached above each eye.
