Meganeuropsis

Meganeuropsis
A while back we learned about Meganeura, a genus of gigantic Dragonflies that lived around 300 million years ago, back when the oxygen levels were higher and the earth could support insects of tremendous size.

So, it should not come as a shock that there were other huge Dragonflies out there, aside from Meganeura. Enter Meganeuropsis, a genus containing two species that rival the previously mentioned insects in size. (It's also important to note that the two genera occupied different areas. Meganerua in what is now Europe, and Meganeuropsis in the middle United States.)

The two known species are M. permiana and M. americana. They were uncovered in Kansas and Oklahoma respectively, back in 1937 and 1940. M. permiana  may be the largest insect ever, even bigger than the Meganeura species.

Unfortunately, it can be hard to tell just how large these insects were able to get, since the fossils had to have very specific conditions in order to stay preserved, and because the parts themselves were so delicate. In short, it is very rare to find these parts intact, so it can be difficult to determine overall size. The largest preserved wing so far  demonstrates a nearly 2.5ft wingspan (the fossil currently resides at Harvard).

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!

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS
