Ancient hedgehog and tapir once inhabited British Columbia

The Earth has experienced many dramatic changes in climate since the dinosaurs went extinct 66 million years ago. One of the warmest periods was the early Eocene Epoch, 50 to 53 million years ago. During this interval, North American mammal communities were quite distinct from those of today. This is illustrated by a study published in the latest issue of the Journal of Vertebrate Paleontology that describes an ancient hedgehog and tapir that lived in what is now Driftwood Canyon Provincial Park, British Columbia, some 52 million years ago.

"Within Canada, the only other fossil localities yielding mammals of similar age are from the Arctic, so these fossils from British Columbia help fill a significant geographic gap," said Dr. Natalia Rybczynski of the Canadian Museum of Nature, a co-author of the study. Other fossils of this age come from Wyoming and Colorado, some 2,700 miles to the south of the Arctic site of Ellesmere Island.

The ancient hedgehog is a species hitherto unknown to science. It is named Silvacola acares, which means "tiny forest dweller," since this minute hedgehog likely had a body length of only 2 to 2.5 inches. The delicate fossil jaw of Silvacola was not freed from the surrounding rock as is typical for fossils. Rather, it was scanned with an industrial, high resolution CT (computed tomography) scanner at Penn State University so it could be studied without risking damage to its tiny teeth. Modern hedgehogs and their relatives are restricted to Europe, Asia, and Africa.

The other mammal discovered at the site, Heptodon, is an ancient relative of modern tapirs, which resemble small rhinos with no horns and a short, mobile, trunk or proboscis.

"Heptodon was about half the size of today's tapirs, and it lacked the short trunk that occurs on later species and their living cousins. Based upon its teeth, it was probably a leaf-eater, which fits nicely with the rainforest environment indicated by the fossil plants at Driftwood Canyon," said Dr. Jaelyn Eberle of the University of Colorado, lead author of the study.

Brandt's Hedgehog (Paraechinus hypomelas)

...a species of desert hedgehog that is native to much of the Middle East and central Asia. Like other hedgehogs Brandt's Hedgehog is mainly nocturnal and will feed insects and other small invertebrates. Paraechinus hypomelas gets its common name from (it was actually named by) Johann Friedrich von Brandt, a director of the Zoological Department at the St. Petersburg Academy of Sciences.

Long-eared Hedgehog (Hemiechinus auritus)

..is a species of hedgehog native to Central Asia and the Middle East. Like other hedgehogs the long-eared hedgehog is an insectivore and will feed mostly on insects and other small invertebrates. As you might of guessed this species of hedgehog sports fairly long ears which help them them with heat radiation in the harsh desert, they also grant them excellent hearing.

Moonrat (Echinosorex gymnura)

Also known as the Greater Moonrat, the moonrat is not a rat or from the moon, but is a species of insectivorous mammal related to hedgehogs endemic to parts of Indonesia. Like its hedgehog relatives the moon rat is primarily nocturnal and omnivorous and feeds mostly on worms, insects, fruit and fish. However unlike hedgehogs moonrats are partially aquatic and will often enter and hunt in water.
