Alamosaurus Bone - Classic Riker Display Case Fragment

The age of dinosaurs saw many titans, but few can compare to the mighty Alamosaurus. From head to tail, Alamosaurus stretched to 85 feet, while its massive legs supported a weight of around 30 tons. Alamosaurus was the largest dinosaur known in North America and one of the last to be marked in the fossil record before the Cretaceous extinction. When seeing the bones of this giant, one has to wonder what the world was like at the end of the Mesozoic... and perhaps what other massive dinosaurs may have evolved, had their time on Earth continued.

This specimen is a piece of fossilized Alamosaurus sanjuanensis bone, recovered from the Javelina Formation in West Texas. 66,000,000 years ago, this was a rich environment along the Western Interior Seaway where Alamosaurus grazed, protected from predators with its natural osteoderm armor.
