Dinosaurs Laelaps trihedrodon, Cope criticizes Dryptosaurus O. W. Lucas collected the first remains of what would later in the year be named Laelaps trihedrodon from Quarry I of the Saurian Hill at Garden Park, Colorado."Introduction," Chure (2001) page 11. Edward Drinker Cope would describe the material later in the year in a short paper titled "On a carnivorous dinosaurian from the Dakota beds of Colorado."Cope (1887) pages 805-806. The "Dakota beds" he references are actually Morrison Formation strata. Cope claims to have a skeleton of unspecified completeness on which to establish the new species, but only describes a partial dentary which has 5 successional teeth, 2 functional teeth, and one tooth missing from its socket. All of the preceding material has since been lost to science with the exception of 5 broken, partial tooth crowns."Description of 5780," Chure (2001) page 11. From the now missing dentary, Cope infers that the creature is a carnivore and compares its dentition to that belonging to other members of his infamous genus "Laelaps", L. aquilunguis and L. incrassatus. Cope concludes the paper with a pointed criticism of his rival O. C. Marsh's attempt to rename Laelaps as the genus Dryptosaurus because the generic name Laelaps has been used in entomology.Cope (1887) page 806. Cope claims that since the mite genus Laelaps was a synonym that the name was not truly preoccupied and Marsh's erection of Dryptosaurus has therefore created a new, redundant synonym of Laelaps the dinosaur. However, subsequent researchers have supported Marsh's new name.
