WDC DML 001
WDC DML 001 (nicknamed "Lori") is an as yet undescribed, substantially complete, fossil of a small troodontid dinosaur from the Late Jurassic Morrison Formation of east–central Wyoming, USA. The presence of this derived maniraptoran along with several others, such as Anchiornis and Eosinopteryx, in Jurassic sediments is a strong refutation of the temporal paradox argument used by those who oppose the consensus view that birds evolved from dinosaurs.
"Lori" is being described by Scott Hartman, David M. Lovelace, and William Wahl, and accessioned by the Wyoming Dinosaur Center. Its discovery was announced at the 2003 annual meeting of the Society of Vertebrate Paleontology, and a phylogenetic analysis including it 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]
In 2001, a field crew from the Tate Museum supervised by Wahl discovered the fossil in rocks of the Jimbo Quarry of the Morrison Formation, overlying the excavation site of Supersaurus vivianae, near Douglas, Wyoming. The stratigraphic position of the site was carefully documented by the collectors and detailed in Lovelace, 2006.[2]
