“History was made last week when the first red leopard was collared by Gerrie Camacho of the Mpumalanga Tourism and Parks Agency, supported by a group of local people.

The first images of this animal were taken in December last year. Since then, Camacho has been trying to track the animal in order to collar it. On January 7 the leopard was darted and sedated and the collar fitted.”

Meet a mysterious mammal relative on this #FossilFriday.

Edaphosaurus boanerges is a distant relative of mammals. The fossil record indicates that it was one of the most common large animals in North America roughly 260 million years ago, about 30 million years before the first dinosaurs. Edaphosaurus, like Dimetrodon, had a sail on it’s back. The two species, however, are not closely related. Their sails are structurally disparate and probably evolved independently. This structural difference only increases the mystery surrounding the function of the sails.

This fossil was collected in Archer County, Texas, and can be found in the Museum’s Hall of Primitive Mammals

The Elusvie Hourglass Dolphin

This elusive mammal is the only species of cetacean to be formally classified without a specimen

by Becky Crew

Named for the distinct white shape along its sides, the hourglass dolphin (Lagenorhynchus cruciger) is found throughout the cold open waters of the Southern Ocean, never straying anywhere warmer than about 13°C.

Rarely seen since its discovery almost 200 years ago, the hourglass dolphin is said to be the only cetacean - a large group of marine mammals that includes whales, dolphins, and porpoises - to have been classified based on eyewitness accounts alone.

In fact, it was declared a new species by French naval surgeons and naturalists, Jean René Constant Quoy and Joseph Paul Gaimard, using nothing but a sketch made as they ran an expedition to the Antarctic in 1824. Fortunately though, with markings as distinct as the hourglass dolphin’s, you’re not likely to misidentify one…
