Welcome back or welcome to my free coloring pages blog.
Today's new drawing is of two of the largest animals in their class
in what is now known as South America.
Notocollosus and Aerotitan from South America
Notocollosus was a larger Titanosaur. They were huge animals. They had an estimated mass approaching 75 tons and maybe even larger. They had the biggest humerus bone of any other Titanosaur. So perhaps it was even larger than Argentinosaurus. The Genus name Notocollosus means "South Wind Giant." The specific name or species name honors a South American Paleontologist: Jorge Gonzales Parejas, who has extensively studied the dinosaurs of Northern Argentina.
The length of Notocollosus is not certain due to an incomplete skeleton. But some estimates of length are up to 92 feet or 28 meters. But that huge humerus may indicate that Notocollosus was the biggest Titanosaur and maybe the biggest land animal of all time! To determine that more fossil evidence must be found. There is also Patagotitan which claims the title of Biggest Dinosaur. Some paleontologists think that Argentinosaurus was the largest dinosaur.
Aerotitan sudamericanas means Airial giant of South America. It is a type of Azhdarchid so it was a relative of Quetzalcoatlus. But Aerotitan is from South America and Quetzalcoatlus is from North America. Aerotitan had a wingspan of 16 feet or 5 meters. (Quetzalcoatlus had a wingspan twice as wide.)
Personally, I like the names given to these two amazing Mesozoic animals!
NOTE: This drawing will be found in printable form by clicking on the "Paleontology" button and scrolling down to the bottom of the"Mesozoic Life" part of the page. New drawings are at the bottom of the correct list. Below are some other drawings from previous posts of other huge Titanosaurs from South America. These dinosaurs will be found further up the list. My wife and I have seen displays of Argentinosaurus and Patagotitan. Seeing the size of these huge Titanosaurs is absolutely amazing. Have fun coloring!!!
