Adult Alamosaurus and Triceratops

Today's newest coloring page that I drew is in keeping with the theme of

Alamosaurus and Triceratops. In this case, they are full-size adults.  

Adult Alamosaurus and Triceratops

There are known dinosaur tracks in Wyoming that are of a mixed herd. So the idea that two herbivorous dinosaurs may have had a friendly relationship is not unheard of.  I have been to that site.  It is called Red Gulch Dinosaur Pathway, and it is east of Greybull, Wyoming.  

A full-sized adult Triceratops had horns that curved forward - like some modern bulls.  Triceratops was around 30 feet long or over 9 meters long.  Triceratops was almost 10 feet or 3 meters tall.  A full-sized adult would have weighed around 13 tons!

Yet an adult Triceratops would have been dwarfed by an adult Alamosaurus.  A full-size adult Alamosaurs may have weighed up to 80 tons and may have been up to 115 feet long.  That is 35 meters long. Alamosaurus probably was not as tall as a 60-foot-tall Sauroposeidon, but it was definitely very tall.  Maybe 40 to 50 feet or 12-15 meters tall. 

Alamosaurus was the biggest land animal ever to live in what is now North America.  Triceratops was the largest of the Ceratopsian or horned dinosaurs.  Also, they lived at the end of the dinosaur period, called the Cretaceous.  The asteroid or comet most certainly wiped them out, but the huge upping of volcanic activity before the asteroid or comet had already made the Earth a very inhospitable place. 

NOTE:  This drawing is found in printable form by clicking on the button labeled "Paleontology" and then scrolling down to the bottom or near the bottom of the "Mesozoic Life" section.  Have fun coloring this last of the series of Alamosaurus and Triceratops.
