Clepsydrops was a small species of amniotes that lived from the Moscovian to the Wordian epochs (otherwise known as the middle Carboniferous to the late Permian). They lived in prehistoric northeastern North America, and hunted for small amphibians such as eocaecilia, and insects such as unsuspecting meganeura
The first clepsydrops fossils were found in Nova Scotia by Edward Drinker Cope in 1877.
These animals were ancestors (or close cousins of the ancestors) of the famous dimetrodon.
Originally, dimetrodon limbatus was identified as clepsydrops limbatus. This was corrected by Cope.
