Meaghan thinks she is oh so clever, making Amy publish blog posts about mushrooms while she was away in Spain. Well, payback's a bitch so this month all y'all bloggers are gonna read about fuckin' giant LEMURS!!
|Welcome to Meaghan's new nightmares++|
|perfect size for spooning!|
Same study, different bone: femoral head diameter predicted a mass of of 244.1 kg (538 lb). Later, in 1995, a study using the midshaft circumference of the humerus and femur estimated a mass of 197.5 kg (435 lb). NOWHERE COULD THE VENGEANCE TEAM FIND ANY STANDARD ERRORS ASSOCIATED WITH THESE MASS ESTIMATES. WTF????

Granted, Amy could not get beyond the second page of the article due to Springer Link charging up the butt for journal access, but in those two pages were absolutely no measures of standard error, nor were any listed on the wikipedia article that includes those citations. Okay, "based on multiple regressions of the femur in 2008, Jungers and colleagues generated the current best estimate of 161.2 kg (355 lb) with a possible range of 150–187.8 kg (330–414 lb)" is getting better, but this is still not satisfying. In paleontology or really ANY science where you are predicting body mass from a bone, you accumulate standard errors from all your regressions and calculations. This standard error is extremely important when judging the validity of a mass estimate. Let's say we use Amy's pinky toe to estimate her mass and calculate a value of 175 lbs (+/- 200 lbs), meaning she's probably 175 lbs but could be 375 lbs or -25 lbs, making the estimate completely statistically insignificant, and therefore not worthy of publication.
So the current idea is that Archaeoindris was the size of a living gorilla, but until Amy gets full access to that journal article or does the study herself, we will have to take that with a grain of salt. So let's just enjoy more photos and random facts in the meantime:
- Bones from Archaeoindris have only been found from one site: Ampasambazimba, central
All of Amy's giant lemur friends are dead. Archaeoindris
looks like a self-righteous asshole, but it still sucks that it's dead.
- Archaeoindris is considered to have been a folivore (leaf-eater) based on wear patterns on its teeth
- Although scientists believe it was a rare lemur, Archaeoindris was still extant when humans first arrived on Madagascar
- Amy was born a mere 3000 years too late to meet the lemurs who would have inevitably become her best friends. We suppose she'll have to settle with Meaghan as a close second.
- Archaeoindris may have been driven to extinction by humans. The bones of another giant sloth lemur (that lived alongside Archaeoindris) Palaeopropithecus ingens, show classic signs of butchering. These include sharp cuts near joints, spiral fractures, and percussion striae (scroll to pg. 9).
|Luckily for Amy, some lemurs survived the hungry humans.|
** still sarcasm
++Amy, just because I am short doesn't mean I'm afraid of everything bigger than a breadbox. Even this much bigger than a breadbox. xoxoxo Meaghan
