Yes, indeed, as noted by others here. These fossil forms have a lot more in common with pacaranas, as the article mentions, and appear to look more like giant capybaras, than giant rats.

Therefore, I have revised the headline to this blog.

The term “rat” is very misleading, as this animals had nearly no connection with rats. What would make at least more sense would be to call it a monster guinea pig, as this south american rodents are in fact closer related to this extinct brute than any rat.

This is a fascinating find. Giganticism is a relatively common evolutionary route for a range of animals throughout the ages as it offers a whole slew of varied benefits even in light of the obvious drawback of having to acquire enough food to maintain such mass. I wonder what key environmental and selective pressures were present in this habitat in this particular case that made it advantageous for this rodent to develop such immense size? It is a very interesting topic for me.

It really does not look like a giant rat at all, but I guess “GIANT FOSSIL RAT” sounds a lot more exciting than “giant fossil capybara”.

I wonder if they were prey for Giant Fossil Cats ?

Just imagine the size of the trap to catch that big mutha!
