Moabosaurus and other Animals from Cretaceous Moab including an Early Iguanodon

 You have found my free coloring pages blog.

Today's new drawing that I have done is of Cretaceous animals near Moab, Utah. 

OK, they were found near Moab, Utah. 

In fact, the largest dinosaur found in the area is called Moabosaurus. 

Moabosaurus on a River Plain

Moabosaurus was a large animal. But it was far smaller than its large Titanosaur cousins. That being said, these Sauropods were still the largest animals in their Early Cretaceous environment. It was 33 feet or 10 meters long. It weighed around 22,000 lbs. or 10,000 kg. It appears that earlier Sauropods had died off in the area or never lived there near what is now the Moab, Utah area. 

Moabosaurus was named after Moab, Utah, by paleontologists from Brigham Young University.  Brooks Britt was the lead BYU paleontologist in this study. The scientific name of this Sauropod is Moabosaurus utahensis. 

There are other dinosaurs in the background. BYU student researcher Stefan Arriscorreta recently presented research that showed that Iguanodons evolved 25 million years earlier than previously thought. They lived in the same area and at the same time as Moabosaurus - around 125 million years ago. Stefan found Iguanodon eggs in the area. This area is now a desert, but back then it was a wet river plain. 

There are two Pterosaurs in the sky. They are also from the Early Cretaceous. They are Uktenadactylus. This was a large Pterosaur with a wingspan of up to 29 feet or 9 meters wide. That is a big flying reptile!

If you are wondering why I included flowering plants, it is because new research is showing that flowering plants were flourishing as far back as 125-130 million years ago. New research has also shown that grass evolved in the Early Cretaceous.
