New Dinosaur from Argentina: Guemesia ochoai

 Welcome to my blog of free coloring pages.

Today's new drawing is of a newly named dinosaur from Argentina.

Guemesia ochoai Adult

Guemesia ochoai Juvenile

A new predatory dinosaur has been identified in Northern Argentina.  It is a type of Abelisaur, like the more well-known Carnotaurus.  Although this new dinosaur does not appear to have the horns that Cartaurous had.  Abelisaurs lived on the Earth for a long time.  The first was found and identified in Australia. It lived 170 million years ago.  This newly identified dinosaur lived around 70  million years ago.  Some species of Abelisaurs lived until the End of the Cretaceous extinction... caused by the asteroid that hit the Yucatan Pennisula 65 million years ago. 

The new species was named Guemesia ochoai.  The genus name of Guemesia comes from a hero of Argentina's independence.  He was named Martin Miguel de Guemes.  The species name of ochoai is for the museum worker who made the discovery.  His name is Javier Ochoa.  Guemesia appears to be an early Abelisaur.  So the other Abelisaurs like Abelisaurs and Carnotaurus may have descended from Guemesia.  

Guemesia was a smaller dinosaur than other known Abelisaurs.  But the holotype fossil is just a braincase so it is thought to possibly be of a juvenile.  The adults may have been up to 26 feet 3 inches or  8 meters long.  The drawings above are of this dinosaur as an adult and as a juvenile.  

NOTE:  These drawings, in printable size, can be found by clicking on the Paleontology button.  Then scroll down to the bottom of the Mesozoic section of the drop-down menu.  Some of my older drawings are not working as far as printing.  So let me tell you a couple of things:  If you search on a search engine for Robin's Great Coloring Pages in images... you will find many of my drawings.  Just click on the Visit button and you will get to the original page with the information I wrote to go with the drawing.  IF you ever get to one of my pages, like this one, you can click on the drawing and copy it.  Then paste it in a drawing or word processing program.  Then you can print the drawing.
