Dinomyidae

Hey kids, welcome back to our series on the mysteries of created kinds!

We took a few weeks off due to some unexpected developments, but now we’re back and heading to South America, where there is a rodent we need to check out. Yes, I know there are a lot of rodents, but this one is not like the ones you might find in your backyard… unless your backyard is the Amazon jungle.

Two by Tuesday

This mammal is largely unknown, though many related genera are known from fossils. They are nocturnal and feed on plants. Based on studies of their brain, this kind is presumed to rely heavily on its hearing rather than its eyesight.1 They prefer moderate-to-heavy tree cover and use rock caves as their homes.2

Has anyone figured it out yet? Guessing this week’s kind is very hard. There simply was not much information available on this kind. This week’s kind is the Dinomyidae, or the Pacarana. These rodents have a lot of extinct relatives, but they are not well known to science and desperately need further study.
