| Mount
of Diplodocus, one of the longest sauropod
dinosaurs from the Late Jurassic. Reaching 27 m
(90 ft.) in length, this is our largest fossil mount.
Though very long, Diplodocus was a relative
lightweight compared with some of the other sauropods
of the period. This mount contains more than 110
vertebrae – nearly 80 in the tail alone. The
skull photo shows the pencil-like teeth designed
for raking vegetation. Top: Photo by Chip Clark,
