Moab will have yet another dinosaur attraction coming this fall. More than 200 reptilian footprints scattered over an area less than a football field have been uncovered after a resident discovered a few tracks while hiking. Dinosaur tracks are known from dozens of locations in this area but this site is unusual because of the […]
Thousands of dinosaur footprints have been found on a steep mountain slope in Denali National Park in Alaska. These are not the first dinosaur tracks to be found in Denali but the size of the tracksite – at least 500 by 150 feet – and the exceptional preservation of the tracks makes this a notable […]
What do you think of when someone mentions the Jurassic or Cretaceous ages? Most likely you will immediately think of dinosaurs and other large reptiles such as pterosaurs. Maybe you think of the movie Jurassic Park and the dinosaurs and lush vegetation. These periods are also known as the Age of the Reptiles and aptly so since many […]
We live in a new golden age of fossil discoveries. It seems that every week a new and dramatic fossil find is revealed. This fossil renaissance can be attributed to the opening up of new fossil sources, particularly China and Mongolia but also South America and to improved technology for retrieving and analyzing fossil remains. […]
A mummified fossil of common species of hadrosaur was found recently in South Dakota that showed that this particular hadrosaur had a rooster-like fleshy comb on its head. Many hadrosaurs have exotic extensions of their cranial bones but this evidence that even the “boring” hadrosaurs had fleshy projections suggests that the hadrosaurs were an even […]
What museum can you go to where you can see real dinosaur bones, you don’t pay any fees, you can touch all the exhibits and there are no security cameras watching your every move (at least I don’t think there are:-)? The answer is The Mill Canyon Dinosaur Trail near Moab, Utah. This outdoor “museum” […]
Yep, dinosaurs are known by more than just their bones. I have been reading quite a few research papers about dinosaurs as I prepare to write a long set of posts about Dr. Schweitzer and the significance of soft-tissue preservation in dinosaur bones. During this reading I got distracted by a discussion about dinosaur coprolites […]
Dinosaur eggs are surprisingly (to the non-biologist) similar in size. Even the very largest dinosaurs laid eggs that were hardly any bigger than the largest eggs found today. These are observations from the fossil record and these observation make sense biologically even though all we see are fossilized eggs. Eggs are limited in the size they attain for several reasons but one of the most important is that the embryos in the eggs must have oxygen to grow.
