Ankylosaurus

Ankylosaurus magniventris
About a week ago we learned all about an armored Sauropod, Ampelosaurus. Today we'll learn about one of the most famous armored Dinosaurs of them all- Ankylosaurus. Like Ampelosaurus, Ankylosaurus lived during the late Cretaceous period... though a few million years later and in a different part of the world.

There is only one identified species within the Ankylosaurus genus-- A. magniventris. It was first uncovered in Montana back in 1906, and officially named in 1908. Ankylosaurus translates to "Curved Lizard" or "Stiffened Lizard," while magniventris means "great belly," a reference to the animal's width.

Ankylosaurus was covered by osteoderms of varying sizes, and those plates most likely had keratin on top of them as well. They also had large, clubbed tails-- those clubs were actually osteoderms fused with the last few vertebrae on the tail. Those plates and club (and the horns on their head) made them a difficult animal for predators to take down.

Ankylosaurus was an herbivore, and had a beak and small teeth that were used to browse from trees. They actually lacked molars, so food wasn't really ground up. Overall, we know a lot about the anatomy of the Ankylosaurus... except for what its feet looked like! No foot fossils have ever been found, though based on the feet of closer relatives, they probably had five toes on each foot.

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

Four!

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!

Binturong

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
