Taynton Stone, Oxfordshire, United Kingdom
is a tooth from the dinosaur Megalosaurus bucklandi from the Middle
Cretaceous Bathonian Stage deposits of the Taynton Stone, Oxfordshire,
United Kigdom. The tooth's fine serrations attest to the meat-eating
habits of this dinosaur. Megalosaurus was the first dinosaur to
be scientifically described. This was by William Buckland and W.
D. Conybeare in 1824, making this a significant historical specimen.
Originally, only the genus was assigned and some
eight years later the species name was given in Buckland’s
Owen coined the term dinosaur, and recognized that Megalosaurus
was indeed one of these “fearfully great reptiles” Like
most dinosaur teeth found, this one was shed. Dinosaurs continually
replaced their teeth so as to keep a sharp set always deployed.
This Megalosaurus tooth came from a large animal. Magalosaurus is
believed to have reached a maximum length of some eight meters making
it a terror in its domain.
