Dimetrodon Vertebra 17.5mm Pre- Dinosaur Permian Texas Red Beds TX COA 6429

Description: Welcome to Pioneer Fossils! A Certificate of Authenticity, which has a color photo on it of the exact item you purchased, will accompany the specimen. Also, a small color picture of a Dimetrodon. Here is a nice rare fossil vertebra bone section from a Dimetrodon, from the early Permian, between 295 to 272 million years ago. From the Texas Red Beds, Archer County, Texas. The last Dimetrodon became extinct 40 million years before the first dinosaur. It measures about 17.5mm using calipers. No paint or restoration has been applied. Dimetrodon was a distant cousin (but cousin nonetheless) to Edaphosaurus, which lived from the Pennsylvanian to the Permian, 303 to 272 million years ago. Many of both species are from the Texas Red Beds and Oklahoma. Edaphosaurus fossil bones can be purchased separately. In the 1940’s, Rudolph Zallinger, an art student at Yale University was asked to paint a mural (fresco) “The Age of Reptiles” in the Great Hall of Yale’s Peabody Museum. He had to choose which plants and animals to feature in his 110 foot mural. For his Permian part of the mural, he chose two “sail-back” reptiles to represent it. These animals are Edaphosaurus, and Dimetrodon. They look similar to each other, with each having a large “sail” on its back. Both Edaphosaurus and Dimetrodon had large sail backs, perhaps for heat regulation. However, Dimetrodon’s sail was formed around elongated neural spines that projected from the vertebrae, held together with skin. Edaphosaurus’ sail also had small horizontal cross-bars on the spines. Neither animal was a dinosaur, both dying out about 40 million years before the first dinosaur. Both were non-mammal synapsids (pelycosaurs), both walked with short legs similar to a crocodile. Dimetrodon was the apex predator, with some large sharp teeth in its mouth. Edaphosaurus had teeth more suited to crushing and grinding, and it probably ate plants, insects, and possibly mollusks. Edaphosaurus grew to about 11.5 feet, while the largest Dimetrodon reached 15 feet. The head of the Edaphosaurus was quite a bit smaller than the head of a Dimetrodon. Both Edaphosaurus and Dimetrodon had a single large opening on each side of the back of the skull, linking them to mammals. Dinosaurs generally had zero or two such holes.We invite you to visit our store. Once inside our store, you will see about a thousand items for sale, and we hope you will love them.

You will receive the exact item described and photographed, unless clearly stated otherwise. This item, along with all items we sell, is only intended for responsible adults. Please keep out of reach of children. All of our descriptions are 100% written by American humans. We will ship this only to the United States. We are not responsible if the buyer reships it somewhere else, after receiving it from us. Our responsibility ends at the destination we ship it to. If you take it out of the United States, you are on your own. COMBINED SHIPPING: We make every effort to combine shipping costs and we refund any overpayment back to you, on the same day we ship the item. We have given hundreds of partial refunds for combined shipping savings. We will do our best to combine purchases to save shipping costs. In some cases, that is easy, in some cases, not as much. Our items are of vastly different sizes and weights, but we never use shipping as a profit center. We would rather refund the shipping overpayment back to you, and have a happy buyer. We are happy to enclose a COA (Certificate of Authenticity). Some words of caution about COA’s: Do not let them become a substitute for learning about the specimens. We have been working with fossils and minerals for many years, and we have seen hundreds of very nice-looking COA’s, some that are wrong, mis-describing a specimen. Have you ever received a Certificate of Authenticity (COA) that had no photo on it of the item you purchased? A COA should be specific to one particular specimen, with a photo of the item on it. At Pioneer Fossils, our fossils and minerals come with a COA, and each have a photo of the exact item you just purchased. This assures that the COA can never be transferred to a different specimen. ****************************************************************************************************************************************** IMPORTANT: If you are not satisfied with your order, please contact us, and let us make it right, before giving any feedback.
