The scientists then worked with an artist to illustrate this ancestor. In addition to a furry tail, the researchers suggest the four-legged creature likely ate insects, weighed from 6 grams (about the weight of some shrews) up to 245 grams — less than half a pound — and was more adapted for general scampering than built for more specialized forms of movement, such as swinging from trees. Also, its cerebral cortex — the part of the brain linked to higher mental processes — was probably convoluted, folds linked with greater brain activity, the researchers found.
i reckon they were a lot bigger than that. they might have been that big at birth, but i reckon they would have gotten a lot bigger as it matured. like that dinosaur i posted with the long tail.
i dun told y'all they were giant rodents.
