Unnamed or unidentified species have been reported on Gerbilliscus robustus and Acomys wilsoni in Tanzania^[8] and on the marsh rice rat (Oryzomys palustris) in Florida and Georgia.^[12]

Synonym of Dryptosaurus

In 1866, an incomplete theropod dinosaur skeleton (ANSP 9995) was found in New Jersey by workers in a quarry belonging to the upper part of the New Egypt Formation.^[13] Paleontologist E.D. Cope described the remains, naming the creature "Laelaps" ("storm wind", after the dog in Greek mythology that never failed to catch what it was hunting).^[14] "Laelaps" became one of the first dinosaurs described from North America (following Hadrosaurus, Aublysodon and Trachodon). Subsequently, it was discovered that the name "Laelaps" had already been given to a genus of mite, and Cope's lifelong rival O.C. Marsh changed the name in 1877 to Dryptosaurus.
