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. The presence of this derived maniraptoran in Jurassic sediments is a strong refutation of the "temporal paradox" (see Temporal paradox (paleontology)) argument used by those who oppose the consensus view that birds evolved from dinosaurs. see Troodontidae.
