Comments

One of the first fossil discoveries to fascinate the Canadian imagination was Bathygnathus borealis, unearthed in 1845 near New London, Prince Edward Island. It wasn't until 1905 that the bone was correctly identified: a fragment of the upper jaw of a sphenacodontid, a member of the mammalian reptile family of pelycosaurs, or synapsids, animals that lived from the Late Pennsylvanian to the mid-Permian. Based on the similarities between the jaws, experts believe that the specimen actually comes from the famous dorsal-sailed Dimetrodon or a similar animal, although no fossil evidence of a dorsal sail has yet been found. If Bathygnathus resembled Dimetrodon, the large "sail" on its back is thought to have served to regulate body temperature.

Despite this falsehood, the fossil still has great scientific and historical significance: the creature lived between 290 and 260 million years ago, when Prince Edward Island was close to the Equator.

Packaging
