Description
editTremacebus was about 1 metre (3.3 ft) in length, and would have resembled a modern night monkey, to which it may have been related,[1] though possibly a stem aotid.[2] However, its eyes appear to have been smaller than the modern species, CT scans of the cranium suggest a relatively small olfactory bulb and poor sense of smell, compared with night monkeys. These features suggest that it may not have been nocturnal.[3] It had an estimated body mass of 1.8 kg (4.0 lb).[2]
Only a few fossils have been found, including a skull from the Sarmiento Formation, Patagonia.[4]
