Researchers give name to ancient mystery creature

For the first time, researchers at the University of Alberta in Edmonton, Canada have been able to put a name and a description to an ancient mammal that still defies classification.

The findings, published recently in the Journal of Paleontology provide the first and only comprehensive account of the creature, named Horolodectes sunae, for the unusual shape of the crowns of the teeth. Horolodectes lived about 60 million years ago, soon after the dinosaurs went extinct, in a period known for its rapid diversification of small mammals. Based on careful examination of tooth and jaw fragments that have been unearthed over the past 30 years, the University of Alberta researchers have now determined Horolodectes was a small fur-bearing animal that measured 10 centimetres in length and due to its powerful jaws, likely had a strong bite.

Most confounding are the animal's teeth, which resemble in superficial ways, those of primitive relatives of ungulates, the group of mammals which includes horses and cows. But despite that link to ungulates, which are traditionally herbivores, Horolodectes was thought to have dined on small insects and grubs. "It had sharp crests on the teeth which formed blades, indicating it was likely carnivorous," said Craig Scott, a PhD candidate and lead author of the study. Horolodectes means 'hourglass biter', in reference to the creature's peculiar hourglass-shaped pre-molars, the teeth between the canine and the molars. The very tall, sharp pre-molars are unlike any others so far discovered in the mammal world. "There is nothing else with teeth quite like it," Craig said.

"In an area of North America that's been fairly well studied, it's unusual to have a critter like this pop up. It's not known anywhere else, just in Alberta. And it's quite distinct. There's no mistaking it," Scott said.

The first dental specimens of the creature were unearthed by University of Alberta paleontologists 30 years ago from the ba
