Troodon Posted October 5, 2015 Share Posted October 5, 2015 The Two Medicine Formation is a late Cretaceous geological formation that was primarily deposited in North Central Montana 84 to 71 million years ago about the same time as the Judith River Formation, See Map - pink area. The Two Medicine is found along the east flank of the Rocky Mountains and represents the upland area of the Cretaceous Seaway while the Judith River Formation represents the lowland area. Although deposited in the roughly the same period the Two Medicine has yielded an amazing list of dinosaurs that are not found in the Judith River. These include Einiosaurus procurvicornis, Maiasaura peeblesorum (Montana's state fossil), Achelousaurus horneri, Bambiraptor feinbergi A good portion of the formation is on Tribal land (Blackfoot Indian Nation) so collecting requires access with Native Americans. I was fortunate not only know a private landowner but a couple of tribal folks. My collection is varied from adults to infant specimens with some being articulated. My first specimen to share is what I believe to be a Euopcephalus sp skull. The very front end is reconstructed so I'm not 100% positive. Around 15" (38cm) Square Condyle Maiasaura peeblesorum A hadrosaur closely related to Brachylophosaurus from the Judith River Fm. An complete articulated arm and shoulder. Has folded its 56" (1.4m) Long. A pair of Unguals - The ventral ridges are diagnostic to this species 8 1 Link to comment Share on other sites More sharing options...
Troodon Posted October 5, 2015 Author Share Posted October 5, 2015 Einiosaurus procurvicornis - A medium size ceratopsian noted for its odd shaped nasal horn. A skull collected by a friend of mine. Nasal Horn Associated Skull elements from a Baby. Incredibly rare Lower Beak Collected from an Einiosaurus bonebed Maxilla and Dentary - may be the only set found with teeth An Ungual Vertebrae Teeth found in an Einiosaurus quarry 7 1 Link to comment Share on other sites More sharing options...
Troodon Posted October 5, 2015 Author Share Posted October 5, 2015 (edited) Achelousaurus horneri a medium size Ceratopsian similiar to Einiosaurus but lacking horns just rough gnarly knobs. My collection includes Frill spikes from an Adult. They are similiar to Einiosaurs however the horizontal spikes are diagnostic to this species. Hypacrosaurus stebingeri is a medium size hadrosaur and one of the most completely known dinosaurs in the world because there are remains from all stages of life from embryo to adult. My specimens support that comment. My first specimen is from a partially articulated infant. The bones on the left of the riker case include associated vertebrae string, leg and arm bones. The bones on the right are from infants. Larger view of foot and includes the smallest ungual and toe bones I've ever seen. Infant Humerus not associated.

Troodon Posted October 5, 2015 Author Share Posted October 5, 2015 (edited) More Hypacrosaurus specimens Dentary and Maxilla Gryposaurus latidens Medium size hadrosaur The only item that I know belong to this species are the teeth. The large denticles on the top of the crown are diagnostic to this species.

Dracorex_hogwartsia Posted October 5, 2015 Share Posted October 5, 2015 Absolutely beautiful! Most of us don't get to see a lot of Two Medicine Formation material. As always, thank you for sharing so much of your collection with us. As you well know, for us dinosaur fossil collectors, this is like kiddie crack!

JohnJ Posted October 5, 2015 Share Posted October 5, 2015 Thanks guys. Like the idea JohnJ of charging admission. Will help fund new digs. You just need a 'key pad' with a few lights and a large "DISARM" button prominently viewable before you show strangers. (Keeps 'em wondering.)

PFOOLEY Posted October 6, 2015 Share Posted October 6, 2015 Beak from Hypacrosaurus HypBeak.jpgHypBeak2.jpg This is quite the specimen.

I always find it interesting what people view as their favorite, its never what I expect. My favorite items are always around infant specimens and the Two Medicine has plenty to offer.

ZiggieCie Posted October 6, 2015 Share Posted October 6, 2015 For those of us from the Ohio, Indiana areas, our fossils are older, but don't have the pizzaze of your collection. Link to comment Share on other sites More sharing options...
-Andy- Posted October 6, 2015 Share Posted October 6, 2015 I love your riker displays. Two Medicine Formation stuff isn't as common as the other formations, but dayum your stuff are more insane than ever. You just need a 'key pad' with a few lights and a large "DISARM" button prominently viewable before you show strangers. (Keeps 'em wondering.) And when he presses the button, the theme of Jurassic Park plays! 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! Link to comment Share on other sites More sharing options...
