Hi, I'm Andrew and I’m just a simple 19 year old guy and zoology student that posts random factoids about obscure animals and general animal science/zoology/biology stuff so if you like animals this is the place for you, if you only like cute animals this is not the place for you… Also I can ID any animals you might need identified (just submit them to me).

Disclamer: none of the pictures are mine unless stated

Family Polioptilidae: A family of passerine birds commonly known as "Gnatcatchers". All gnatcatchers are native to the New World, being found in both North and South America. Gnatcatchers are close relatives of the wrens and some species are known as "Gnatwrens".

Genus: Aelurodon

…A extinct genus of bone-crushing dogs that existed in middle Miocene to early Pliocene North America. Like other borophagines this genushad powerful teeth and jaws that were used crush bones. They also had dew claws on their hind legs, a trait not found in modern wild dogs but is found in domestic dogs. Members of Aelurodon were somewhat smaller than most of their borophagine counterparts (like Borophagus and Epicyon) and were around the size of a modern wolf, some larger species like A.ferox were even thought to be pack hunters like wolves.
