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".

Amargasaurus cazuai

…is a species of short-necked dricarosaurid sauropod dinosaur from early Cretaceous of what is now South America. A.cazuai was small as far as sauropods go, as it was “only” around 10 meters long. Armagasaurus is noted for its upward projecting vertebral spines on its neck and back, their exact function is unknown but they might have supported sails that could have been used for defense, communication, mating, or temperature regulation. Like other sauropos Amargasaurus was a herbivore and fed on plant matter.
