Diplodocus longus

Part of the GIANTS OF THE LAND Exhibit

Late Jurassic Period, approx. 154-152 million years ago

1:2 Scale Skull Replica

SPECIMEN PROFILE

Diplodocus longus was a long-bodied sauropod dinosaur inhabiting the vast floodplains and semi-arid environments of Late Jurassic North America. It is among the most recognizable members of the diplodocid lineage, characterized by extreme body elongation and a highly specialized feeding strategy.

Its long, whip-like tail and extended neck created a highly efficient horizontal browsing system, allowing it to strip vegetation across wide areas with minimal movement of the body. Peg-like teeth at the front of the jaws suggest a feeding method focused on raking and stripping foliage rather than heavy mastication. Its lightweight skeletal structure, reinforced by air-filled vertebrae, allowed for such extreme proportions while maintaining structural efficiency.
