Dromaeosaurus albertensis is a mid-sized theropod dinosaur best known for the sharp sickle-like claw on each foot. Our information on the skeleton of Dromaeosaurus is small indeed, as this taxon, first discovered by the dinosaur hunter, Barnum Brown in Canada in 1914 is known from only a few partial specimens.

Although Dromaeosaurus is widely reported to be found in sediments below the Lance Formation, where our quarries are located, Dromaeosaurus teeth are reported consistently from the Lance, and on that basis we have assigned the dromaeosaur-like teeth In our quarry(left) to Dromaeosaurus.

The assignment to this taxon is based upon the size and shape of the tooth and to the denticle arrangement and count. Denticles are the tiny serrations found on the front and rear surfaces of the teeth of most theropods (see denticles in photo on left).  However, we must say that the assignment to Dromaeosaurus is tentative until such time as we record the teeth in an actual skull of that genus in the Lance Formation.  This is a cast of one of the skulls known to be a dromaeosaur.

Below is a Dromaeosaurus skeleton in jigsaw puzzle form.  If you can correctly assemble the puzzle you will be admitted to the portion of the collection with all of the Dromaeosaurusbones. (To skip the puzzle, click on the link below the puzzle.)
