Cretaceous Ankylosaurus Armor/ Scutes

Kinda looks like just rocks don’t they? “Leaverites” Knowledge is power I point out.

Dinosaurs often had chunks of bone growing on their skin to act as armor. “Osteoderms” are commonly known as Scutes. Many creatures have them. Crocs and Alligators come to mind. Skin surrounded these bony armor chunks They fit tightly in a network of armor to protect the turtle shaped dinosaur with the clubbed /spiked tail from bites. These are remarkably rare. I’ve found these three in 20 years. I’ve found way more T-rex teeth for example and they aren’t exactly growing on trees up here lolol. Ankylosaurs were 20 feet long and 5 foot high at the hips.

Out of curiousity I looked up some pricing on similar items on the commercial market (I have NEVER sold and never will sell a fossil). The smaller one would be in the 500 dollar range and the larger in the 1000 dollar range. I knew they were uncommon but I didn’t know there was a demand for them. Ankylosarids are rare in the upper Cretaceous. Again, they are NOT for sale. They are in the ranch collection of over 10K fossils at this point.

Disclaimer: The Bliss Dinosaur Ranch is 99 percent private land. Deeded ground is the only place it is illegal to collect ANY vertebrate material (if it had a backbone, leave it alone) on public land. BLM, state and Tribal land is off limits. See a turtle shell, leave it lay. On government ground, artifacts from humans are also best left alone. They can definitely get you in big trouble. Invertebrate fossils and wood are a different story. I suggest the Bureau of Land Managements website for further information.

Our ranch is completely covered by the Cretaceous Hell Creek/Lance Formation. Problem is, there is a lot of grass here too lolol.

Dinosaur: Pachycephalosaur Phalange… Hoof/Toe (Real Big Wyoming Critters lolol).

I have read that Pachycephalosaur fossils of any kind constitute only about 1 percent of the fossil record. This toe nail’s journey started 66 million years ago in a sand choked river flowing to the eastern sea. The Hell Creek/Lance Formations (uppermost Cretaceous) is a terrestrial deposit consisting of 700 feet of sand. We have the upper 3 or 4 hundred feet of the formation exposed on our ranch. Of course we are a grassy ranch so somewhere under that grass is a REALLY NICE fossil but I can’t see it. I might have driven over the complete t-rex a hundred times and would have no idea. 

I have found 25 micro-sites…sand deposits of coarsely sorted sands mixed with small fossils. Many teeth, small bones, fragments of almost anything alive in the environment besides dinosaurs.. Even occasional really nice claws come out of the micro-sites. 1 amazing bone bed exists on my ranch that I’ve located. I have mined that location for 17 years now. I call it the “Horn Sieve bed because of the 30 (ish) triceratops horns that have come out of the dig over the years. The dense bone and hydrodynamic shape combined for more of those to drop out of the rivers current at my particular “bend in the river”. The current dropped here and dropped all that dense bone on the river bed. The light stuff kept on going down river. 

Most Hell Creek Bone that I’ve collected has been transported by river systems. Often soon to be fossils were buried and re-excavated several times as the big rivers swept back and forth on the alluvial plain. Lots to know about dinosaur and paleoenvironment lolo.
