My Jurassic Park - Ankylosauria Hell Creek/Lance Formation


Troodon

Recommended Posts

Only two Ankylosaurs are reported from the Hell Creek and Lance Formation the Nodosaurid Denversaurus schlessmani and Ankylosaurid Ankylosaurus magniventris.  I've identified my material to reflect these dinosaurs and if additional ones are discovered will change my identification.  Material from these dinosaurs are extremely difficult to find with Teeth and Scutes being the most common.  Bones are extremely rare. 

 

My Tail Club - also have a container full of isolated pieces that go to the missing portion.

A few representative scutes from my collection.  Most come from one area and are most likely associated.  Have +30 from this site.

I call this my Bactrian Camel double humped scute.  Different locality with a bulbous base.

A digger friend on mine found these Osteoderms "scutes" in South Dakota.  The color variations reflect that it was in found in multiple pieces scattered over a wide area and had to be put together like a puzzle.  Again I have a bag of pieces that don't fit.  Its quite large the bigger one around 23 cm long.   The person I purchased it from did a great job and contacted paleontologist Mike Burns and Jim Kirkland for their opinion since it was a very different osteoderm.  They both believe it looks closest to Glyptodontepelta a Nodosaurid described from the Late Cretaceous of New Mexico.  Glyptodontepelta was originally described in 2000 but thought to be a dubious dinosaur but Mike et al paper concurred that it was a valid dinosaur.   So it all this is true it may be a new species of Nodosaurid from the Hell Creek

Awesome stuff!

Happy hunting,

Impeccable pieces as always. I especially like your new way of photographing your specimens.

Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

Matrix screening under a scope sometimes pays off.   Talked to a couple of my dinosaur buddies about this tiny tiny tooth and we all agreed on the ID.  Of course it's subject to revision :). We don't think it's a Nodosaur or Thescelosaurus.
