Troodon Posted November 19, 2015 Share Posted November 19, 2015 (edited) My next addition to "My Jurassic Park" is with a single species the Hadrosaur: Edmontosaurus annectens. In the late Cretaceous Edmontosaurus was one of the largest and very last Hadrosaurs to exist. It roamed the western North America 66 million years ago and remains are found in its Maastrichtian deposits. Herds of these animals must have been awesome to watch because they were about the size T-rex around 40 ft (12m) long and a great food source for them. All my material was collected from the Hell Creek and Lance Formations. I refer to only one Hadrosaurs species in these deposits based on the 2011 results of a study I noted in the attached post. http://www.thefossilforum.com/index.php?/topic/56733-hadrosaurids-did-you-know/ Although not has sexy as a theropod teeth Hadrosaur teeth functionally are very impressive. In a 2012 study researchers showed that Hadrosaurs evolved extremely sophisticated teeth, more sophisticated than modern mammalian herbivores such as bison, horses and elephants. The study demonstrated that unlike most mammalian molars and pre-molars which are composed of four major tissues the duck-bills evolved a six tissue dental composition which improved the teeth’s ability to grind up food. Hadrosaurs have been identified as “walking pulp mills“ or "Cows of the Cretaceous" and researchers have declared the duck-billed teeth lined jaws as one of the most sophisticated grazing and grinding mechanisms ever to evolve in terrestrial mega herbivores. Their teeth are more complex and better adapted to grinding than most of the large plant-eating mammals found today. A front view of the skull you can see how the tooth batteries are positioned and a cross section of a tooth One of the crown jewel of my collection is one of the finest Edmontosaurs sub-adult skull in captivity at 44" (1.1m) long. Its complete with a partial cervical column and it's preservation is awesome. Still in the field jacket I have yet to decide if I'm going to get it prepped it or just leave it alone A great view of the dentition comes from one of the most interesting specimens I have, an upper and lower jaw section that are fused together. Front Side view I have a few maxilla's in my collection. My favorites are a couple of Juvenile/Baby ones, both are 6" long. An adult specimen can be 17" long.

Troodon Posted November 19, 2015 Author Share Posted November 19, 2015 (edited) The hands of a hadrosaur were full of bones and contained up to 20 different types. Example of what one looked like Carpals in my collection, never can have too many , never tried to put a hand together just too difficult with all of the sizes Carpals: Finger carpals Hand Terminal Unguals Edited November 19, 2015 by Troodon 2 Link to comment Share on other sites More sharing options...

caldigger Posted November 19, 2015 Share Posted November 19, 2015 I do not see any fossils as you describe them...all look geologic in origin, maybe just suggestive shaped rocks. Ya, right! Are all these luscious fossils you keep posting in your house?! Or do you live in the basement of the Smithsonian? Man, you have an incredible collection and are undoubtedly the envy of most on this forum. Keep um coming. Link to comment Share on other sites More sharing options...
Troodon Posted November 19, 2015 Author Share Posted November 19, 2015 You find lots of pathological bones with hadrosaurs here are a few examples. These two unguals are associated. A vertebra with the spine showing healing Finally my example of mummified skin 1 Link to comment Share on other sites More sharing options...
Runner64 Posted November 19, 2015 Share Posted November 19, 2015 Outstanding! Your collection is wonderful. I can't believe you even have a skull too! Wow. Thanks for sharing with us, can't wait to see the rest of your collection! Link to comment Share on other sites More sharing options...

Dracorex_hogwartsia Posted November 19, 2015 Share Posted November 19, 2015 (edited) I was thinking the same thing as caldigger. How big must your house be?! Not only are we all impressed with your fossil collection but I'm sure we would all be just as impressed with your house!
