Shuvuuia deserti
Meet Shuvuuia, a small Cretaceous Dinosaur that was most likely covered in a coat of feathers! The type fossil of the species was found with many deteriorated structures surrounding it, structures that were similar to the central shafts of modern bird feathers. Further analysis showed that these structures once contained beta-keratin, but not alpha-keratin, which gives further evidence towards a feathery coat (as only bird feathers have beta-keratin, but not alpha).

Aside from the feathers, Shuvuuia had a few other bird-like traits. Their skulls, legs, and feet were all very similar to those on birds, but their arms are not, leaving them still within the realm of the Dinosaurs.

Shuvuuia even has a bird name, literally! Their genus is named for the Mongolia word for bird, shuvuu, as the fossils were found in Mongolia. Shuvuuia dates back between 85 and 75 million years, putting it in the Late Cretaceous period.

These Dinosaurs were very small, standing only a foot or so high and having a full body length of 2-3ft. They probably ate insects and small mammals, and were most likely very quick on their feet. All that we know about Shuvuuia comes from only a few fossils, so there is still very much to be learned and uncovered!

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a


For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!


The Binturong ( Arctictis binturong ) also has an equally awesome alternate common name, the Bearcat! However, it really isn't much of a bear OR a cat. While it is true that it is part of the Feliforma suborder, it is not a member of family Felidae. Binturongs are a part of their own family, Viverridae, which is shared with Civets, Linsangs, and Genets. There are six subspecies of Binturong, all of which have slight differences based upon location and habitat. Binturongs range in body size from 60-100cm in length, (not including their tail which has roughly the same length) and weigh between 20 and 30lbs. Binturongs are nocturnal animals native to the rain forests of South East Asia. The species range spans through several countries including China, Malaysia, Indonesia and the Philippines. They are tree dwelling mammals, and have fully prehensile tails that basically double their body length and can be used to cling to the trees or to grasp food. Binturongs are phe
