Hello everyone! It's time for this months Patreon choice video!
This month I was thrilled to see my patrons come out to support one of my favorite clade of animals, the Xenarthrans!
This odd group contains tree sloths, anteaters, armadillos and the extinct Glyptodons, Pampatheres and Ground Sloths! And the recent poll I did on Patreon showed that my patrons love this group of odd mammals just as much as I do!
As a result today I am going to be talking about a species of sloth that many people have probably never heard of. Megalocnus rodens, this small sloth hid away on islands in the Caribbean and managed to survive much longer than most of it's giant relatives on the main land. Dying out less than 4000 years ago?
We have also found a pretty decent amount of fossil evidence of this creature... Which brings up the question why have most people never heard of this animal?
If you would like to vote on future Patreon poll videos, you can join the Cyanobacteria Army and help spread the glory of the goo!

Island dwarfism/gigantism is perhaps one of my favorite evolutionary tendencies. A few years ago I visited Malta and went to a museum that exhibited pony sized elephant and hippo remains found in a cave there. Also the abundance of bones found in the cave sediments suggests such a huge quantity of animals considering the size and dryness of the island. Then again the mediteranian sea dried out several times so the island might have been bigger at the time. Anyways, this kind of stuff is so fascinating even to someone like me who doeant actively study this topic.

The giant ant eater is a badass animal, they are able to handle themselves surprisingly well in the face of predators like jaguars. The giant anteater is an animal that almost looks like a ground sloth if you squint really hard which also contributes to its awesomeness, its just a very underrated animal.
@Rodrigo_Vega
@Rodrigo_Vega Год назад
I personally don't have to squint hard at all. I see them as just long-snouted ground sloths and I had to double check they aren't in fact more closely related to ground sloths than tree sloths. .. they aren't but they are both close. It's all _Pilosa_ . The _Xenarthra_ are not armadillos and glyptodons are all quite closely related.

There are four superorders of placental mammals, Xenarthra, Afrotheria, Laurasiatheria, and Euarchontoglires, among the Xenarthra superorder, there are two extant orders, Cingulata (Armadillos and Fossil Relatives) where the armadillos (family Dasypodidae) are the sole extant family and Pilosa (Sloths and Anteaters), which contains ten extant species within five genera, four families, three superfamilies, and two suborders, the suborders of pilosans are Vermilingua (Anteaters) with only the superfamily Myrmecophagoidea (Modern Anteaters), which contains the families Cyclopedidae (Silky Anteater and Fossil Relatives) and Myrmecophagidae (Giant Anteater and Tamanduas) and Folivora (Sloths) consisting of two monotypic superfamilies, Mylodontoidea (Two-Toed Sloths and Fossil Relatives) with only the monotypic family Choloepodidae (Two-Toed Sloths) and Megatherioidea (Three-Toed Sloths and Fossil Relatives) with only the monotypic family Bradypodidae (Three-Toed Sloths).

@indyreno2933 Год назад
@Vernon Fridy, actually, Cingulata contains only one extant family, which is Dasypodidae, "Chlamyphoridae" is not a valid taxon, there is only the subfamily Chlamyphorinae (Fairy Armadillos) within the family Dasypodidae, glyptodonts are a separate family (Glyptodontidae) grouped with the pampatheres (family Pampatheriidae) under the superfamily Glyptodontoidea.

@PaleoAnalysis
@PaleoAnalysis Год назад
I stumbled upon that when researching this video. Apparently it was originally thought to be a phorusrhacid before they realized that it was just an owl that had evolved convergently. However I would say that it would be highly unlikely for Ornimegalonyx to prey on Megalocnus because there was still a considerable size difference between them. More than likely Ornimegalonyx would have fed on either other birds or smaller mammals like primates.
@PaleoAnalysis

For a comparison, a Harpy Eagle is a large predatory bird but it still doesn't hunt Tapir. That's about the same size difference.
