Robin's Great Coloring Pages: Parasuarolophus the Large Crested Hadrosaur or Duck-billed Dinosaur coloring pages

Welcome to my free coloring pages blog.

The new drawing today is of a Hadrosaur or Duckbilled Dinosaur called Parasaurolophus.

Parasaurolophus by a River

Parasaurolophus was one of the larger Duck-billed Dinosaurs. Duck-billed Dinosaurs are also called Hadrosaurs. Parasaurolophus had a large hollow crest that had a divider in it. So sound could travel up one side of the crest and back down the other... like a trombone. The males had larger crests than the females. So males had a deeper "voice" or honk.

It is thought that Parasaurolophus could communicate with honks or blasts from either their mouth or nose. There is even one hypothesis that they could, as a herd, make such a blasting noise that it could serve as a defense mechanism against Tyrannosaurs.

The flowers on the bushes are not a mistake. They are there because fossilized pollen has been found from the era BEFORE dinosaurs. So flowering plants WERE around during the Mesozoic Era or age of reptiles. The grass is also not a mistake. Grass seeds have been found in Hadrosaur coprolite. or fossilized droppings. There were 5 different kinds of grass seeds so we know that grass had already radiated into different species by the time the Late Cretaceous came along.

Parasaurolophus lived in the Late Cretaceous, but not right to the end. More precisely Parasaurolophus lived between 76.5 and 73 million years ago. They lived in what is now North America and possibly even in Asia. They grew up to 31 feet long or 9.5 meters long. They weighed up to almost 3 tons. That would be 6,000 lbs. or 2,722 kg. It was probably preyed upon by the early Tyrannosaurs Albertosaurus and Gorgosaurus.

NOTE: This new drawing is to be found by clicking on the Paleontology button and then scrolling to the bottom of the Mesozoic section. Below are some older drawings of Parasaurolophus. Some of them might not print due to a problem caused by a new security update. I am trying to get that fixed. The new drawing will print fine.
