[quote]Known from a single specimen, [I]Bathygnathus borealis[/I] has a long and intriguing taxonomic history. It is the second vertebrate fossil named from Canada ([I]Dendrepeton acadianum[/I] was named a few months earlier) and the first non-mammalian synapsid ever found.
Originally collected on Prince Edward Island, Canada, in 1845, the [I]Bathygnathus[/I] specimen was not formally named until 1853, and described in 1854 as the dentary of a bipedal saurian.
“Subsequently, it was erroneously considered a dinosaur until the specimen was recognized as a theriodont in 1876, and later identified as the partial snout of a sphenacodontid,” Prof. Robert Reisz from the University of Toronto and his colleagues wrote in a paper in the Canadian Journal of Earth Sciences.
Using family trees and imaging techniques to see the internal anatomy of the fossil, Prof. Reisz and co-authors found that the eight preserved teeth linked the fossil to the Dimetrodon group – the first terrestrial animal to have ‘ziphodont’ teeth.
“These are blade-like teeth with tiny serrations along the front and back of the teeth, similar to a steak knife,” Prof. Reisz said.
“The roots of these teeth are very long, around double the length of the crowns. This type of tooth is very effective for biting and ripping flesh from prey.”[/quote]
God damn it
So what if it's not a dinosaur. Proto-mammals are cool.

Agreed, still cool no matter what it is classified as.

You're right, shame on zillamaster for spelling 'soory' incorrectly.
