This is my free coloring pages blog.
Today's new drawing is of a large Ceratopsian dinosaur called Torosaurus.
(today's new drawing)
Torosaurus was a large three-horned Ceratopsian dinosaur. It lived more or less at the same time as the similar dino we know as Triceratops. Triceratops was larger at 30 feet or 9 meters long. Torosaurus was around 25-29. feet or 7.6 - 9 meters. Torosaurus is thought to have weighed up to 13,000 lbs and Triceratops was up to 20,000 lbs. So although the biggest Torosaurs were about as long as the biggest Triceratops, the Triceratops were much more heavily built.
Both of these Ceratopsian dinos lived in North America in the late Cretaceous Period. They must have competed for territory and feeding grounds. In a fight, Triceratops would have won due to its more massive mass or weight and therefore much more powerful muscles.
Some paleontologists have hypothesized that they represent the same species but there is a lot of evidence that they are separate species. For another difference besides size, the Torosaurus have two large holes in their frill. But Triceratops had a much thicker frill with no large holes.
Here is a Triceratops drawing I did previously. Note that it has a shorted frill compared to Torosaurus. The frills are also different in shape. By the way, "Torosaurus" means "Bull lizard."

NOTE: The NEW drawing is found, in printable form, by clicking on the "Paleontology" button and scrolling down to the bottom of the Mesozoic part of the list. The older drawing is found by searching further up the list but still in the Mesozoic section. Below are a few other Triceratops drawings I have done over the years. These drawings were all posted previously on this free coloring pages blog. Also, notice the bulls-eye pattern on the Torosaurus and some of these Triceratops drawings. These bulls-eye patterns, especially the ones on the frill, are present in some modern animals so it is thought that the pattern may have been present in Ceratopsians to make the horned dinosaur look larger because the spots would look like big eyes.
