Tuesday, April 21st: Our Mystery Fossil Revealed

What was your final guess on what the skeleton from “The Great Fossil Find” was last week?
Did you get something like this?

It was a pterosaur!
(pronounced “ter-a-soar”; the p is silent)

Look carefully at the skeleton above.  Here are some things I want you to notice:
1. The backbone is made up of lots of smaller bones called vertebrae.

2. Rib bones are attached to the back bones.

3. The LONG wing bones are actually a very long finger!

4. This pterosaur had really sharp teeth (you can see that better in our skeleton from last week) which tells us that it was a predator that ate other animals.

What did you get right?  What did you have mixed up?

On any sheet of paper, create two columns and compare/contrast your skeleton with the pterosaur skeleton above:
