American Mastodon

The American Mastodon (Mammut americanum) was a large tusked mammal that inhabited North American during the late Pleistocene from about 3 million to 11,000 years ago. They stood between eight and ten feet at the shoulder and weighed around 10,000lbs. Mastodons had stocky legs and long hairs covering their bodies. They also had massive tusks, which where more straight then those of their Mammoth cousins.

American Mastodons shared their Pleistocene homes with Mammoths. Though they both belong to the order Proboscidea, Mastodons are classed in the ancient and now completely extinct family of Mammutidae, while Mammoths shared the family of modern Elephants, Elephantidae. The American Mastodon was only the last of the Mastodon line. Members of the family appeared in Africa nearly 40 million years ago, and other species existed in Europe in Asia until about 2 million years ago.

Mastodons had low, ridged teeth that demonstrate a diet based on leaf browsing. This differs from the teeth of Mammoths which were used for grazing. Another distinction between the two is that the mouth of a Mastodon contained more teeth at one time than that of a Mammoth, though they shared the same number of overall teeth in a lifetime. The conical teeth of the Mastodon are the inspiration for their name. Mastodon means "nipple tooth."

Just this past Sunday it was reported that a new skull of what is believed to be a Mastodon was found in a mine in New Mexico. It measured eight feet long. Unfortunately, the skull crumbled during the excavation process, and will now be painstakingly reassembled. Mastodon fossils are relatively common throughout the United States, especially in the Midwest. A majority of these sites contain Mastodons dated between 40,000 and 11,000 years.

Greater Kudu

Tragelaphus strepsiceros The Greater Kudu is one of the largest Antelope species out there, which the largest males standing over 5ft tall at the shoulder and weighing over 600lbs. They sport horns that equally as impressive in size-- the record is 72in. You'll find the Greater Kudus in southern and eastern Africa, where they inhabit scrub woodlands. Their brown coloration and white stripes allow them to remain camouflaged within these woody surroundings. The Kudus are most active at dawn and dusk, and spend the daytime hours hidden in these forested areas. However, their stripes are not their only defensive mechanism; they also sport very large ears that allow them to hear approaching danger. When alerted, the Antelope can try and bound away to safety. Female Greater Kudus tend to live in moderately sized groups with other females and offspring. Most mature males are solitary, and will only join up with these herds during the breeding period that corresponds with the end

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!
