Subadult Alamosaurus and Triceratops

 This is my free coloring pages blog.

Today I am continuing with the theme from my last post.

This is a drawing of two subadult dinosaurs.

Subadult Alamosaurus and Triceratops

Yesterday I drew two young juvenile dinosaurs.  These are the same species, only in a more serious drawing.  They are not full-sized adults.  They are subadults. I guess they remained friends as they grew up.  This sometimes does happen with modern animals of different species. 

Alamosaurus has recently been upgraded.  That is, its size is now estimated to be between 90-100 feet long and weighing between 70 and 80 tons.  That is around the size of the biggest known dinosaurs, Argentinosaurus or Patagotitan.  Paleontologists looked inside the bones and discovered that the fossil showed that the Alamosaurus specimen was not fully grown.  

You can tell this is a subadult Triceratops because the horns point out at an angle.  Full-grown adult Triceratops were bigger, and their horns curved and pointed forward.  If these two were full-sized adults, then the Triceratops would be much smaller in proportion to the Alamosaurus. 

NOTE:  This drawing is found in printale form by clicking on the "Paleontology" button.  Then scroll down to the bottom fothe Mesozoic Life section of the list.  Have fun coloring these dinosaurs!
