More than 8 articulated and disarticulated skeletons and skulls.
The first dromaeosaurid remains to be described were those of Dromaeosaurus albertensis
("running reptile") which were discovered near the Red Deer River by
Barnum Brown in 1914. Unfurtunately as in often the case with many
fossil species, the specimen that Brown collected was far from
complete; it consisted of the partial head, lower jaws and an
assortment of foot bones of a small carnivorous dinosaur.
During the next fifty years nothing more was discovered of this
dinosaur. But in 1964, Grant Meyer and Professor John Ostrom of Yale
University, found a new fossil locality in southern Montana. During the
next two years excavations at this site unearthed several hundred bones
of an entirely new carnivorous dinosaur: Deinonychus ("terrible claw" ) antirrhopus.
