In the 1960’s and 1970’s they discovered a fossil skull, in which they estimated that it lived 66 million years ago! In 1979, they found a second bone of the same dinosaur in Arizona. While trying to decipher the fossilized remains, they realized the skull is not the same as the skull previously found in Utah.
The Dinosaur Skull in Utah:
And as an aside, it seems that the dinosaurs known as “Paleozoic”, “Middle Jurassic”, and “Cretaceous” dinosaurs were all on the plains some 66 million years ago! This dinosaur skull will certainly be a fun find for paleontologists, who will have spent thousands of hours to decipher all of the fossil remains.

As a personal thing, I love dinosaurs. I have an assortment of different specimens that I own, including the first Tyrannosaur bones I found on eBay, and I have a couple dinosaurs I brought back from my expedition with me. Now I’m not quite sure if the fossils I own are dinosaurs or birds, but I’m certainly grateful to the folks at the Utah Paleontology Center for getting me a couple things for free. Even though I probably shouldn’t, my mind is forever occupied with the idea of finding a Tyrannosaurus Rex somewhere. If anyone would like to hear my musings on dinosaurs, check out the links below.
I started this blog by posting photos of the dinosaurs I found from the book Dinosaurs Of Utah by Ron Kagan, along with the actual text. For a lot of information about dinosaurs, especially more detailed information on some of my favorite kinds of dinosaurs, check out the book The Lost World of Cretaceous and Jurassic Dinosaurs by David Evans, which is set to be published by Orbit Books in the summer of 2016, and the movie based on the book.

I’ve updated the post in light of the publication of the book Cretaceous and Jurassic Dinosaurs , and the release of a DVD that contains the entire movie. Now there are some dinosaurs I had originally placed into the Jurassic branch as of the end of the Cretaceous. I’ve also removed more dinosaurs from that branch and placed them in a new branch known as the Maastrichtian - Maastrichtien group. I will update this post as and when I find further details for the dinosaur lineages from all of this material published in books, so keep checking back to this post for updates, or check out Dinosaur Movie News: Jurassic Park 2 (2009) is now available!
