I saw this rat dead yesterday, near a Solenopsis Saevissima colony and I was going to remove it but then I saw millions of ants under it, then I decided to let them have some fun.
This morning they covered the rat with dirt, looks like they are expanding the colony into the rat's body. Also seen Odontomachus sp. and some Camponotus around the area, maybe they are trying to defend their food by doing this. Their colony is under that rock that is visible in the picture.
