WDC DML 001 is the number of a substantially complete troodontid specimen. It was found in the Late Jurassic Morrison Formation of western North America.
The fossil was found in Wyoming. WDC DML 001 has not yet been officially named, but the specimen is nicknamed "Lori". Lori will be described by scientists from the Wyoming Dinosaur Center, a small natural history museum in Wyoming.
A phylogenetic analysis was presented in an abstract for the Journal of Vertebrate Paleontology in 2005. The phylogenetic analysis placed the specimen as a close relative of Sinornithoides.[1]
This dinosaur is very significant because it is the oldest known troodontid. Until the discovery of Lori, troodontids were believed to have first originated and evolved in Asia and then migrated to North America. Most troodontids were discovered in Asia, and the previously oldest known troodontids, from the Lower Cretaceous, lived there.
