Mosasaur Gnathomortis (Previously Prognathodon) stadtmani found 1975 Cedaredge, Colorado

Recommended Posts

My name is Gary L Thompson I am the sole discover of the Mosasaur Prognathadon stadtmani that currently resides at BYU, This specimen was found in Cedaredge, Colorado in 1975. It took over 40 years to get the complete casting of this mosasaur. I thought maybe this might be a story of interest for you since this is an extremely rare fossilized specimen from about 85 million years ago and the fossilized marine reptile is the only one ever found on the western side of the prehistoric sea that once covered an area ranging from Utah to Kansas and Nebraska. It was a ferocious creature approximately 35 feet long. The excavated skull bones remain the property of Brigham Young University’s Paleontology Museum."  

 

I just wanted update every one on some misleading information regarding the find and to send the most current information updates. It appears that the Genus name is probably going to change to a brand new Genus, the scientific community is still discussing this one, will try to update when that happens. 

 

BYU has now completed the entire skeleton and now have it up as of the beginning of the year. I have included current photos of it along with "My true story" and all corresponding credits for the find, scientific research and preparation of the specimen. I just thought these might be of interest to you. The photos are from the BYU webpage.

What a beautiful monster! Thank you for sharing your journey with us.

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!
