Summary edit

Description

Fossils of ichthyosaurs, fish-shaped reptiles that lived during the dinosaur era.

Ichthyosaurs are my favorite extinct animals. Gracefully shaped like dolphins, they pretty much were dolphins of their day - except that while dolphins are mammals, these creatures were reptiles. They breathed air, and gave birth to live young. Ichthyosaurs lived worldwide, though the largest known colony was in the vicinity of Oxford; Britain was a warm, shallow sea at the time, and Oxford's clay layers, dating back to the dinosaur era, nicely preserved large numbers of ichthyosaurs.

Another known ichthyosaur population existed in the US state of Nevada, near the ghost town of Berlin. Plate tectonics caused the Nevada seafloor to eventually rise to an elevation of 7,000 feet today; Berlin is home to the largest ichthyosaur fossils ever found, and I had visited it in late 2000.

All marine reptiles went extinct at the end of the dinosaur era, with the sole exception of the turtle family.
