Sapismorex panamensis (The Rotting King of Panama). Sapismorex is a medium-sized Tyrannosaurid theropod from late Cretaceous Panama. While resembling Albertosaurus and Gorgosaurus in a skeletal and musculatural view, they differ from their brethren in a significant way; they imitate a cadaver to fool their prey, scavengers, hence the name.

Ranging from 9 to 11 metres long and 3 to 3.8 metres tall, they are unrivalled in their environment as the largest theropod in the region and ecosystem.

Their patterns are intricately detailed, often including flesh, rot, bone, stringy tendons and blood vessels. However, their disguise isn't always perfect, as seen with their "neural spines" on the skin, and not on the "flesh".

Colouring varies greatly and is often so. Very rarely do two specimens look identical.

Sapismorex are often littered with detritivore partners. The symbiotic relationship benefits both. While the partners can siphon a controlled amount of nutrients from the bloodstream, the appearance also lures more prey, making the exchange beneficial for both parties. Another partner includes a species of microorganism (similar in niche to the red tide algal blooms) that lives in the saliva of Sapismorex, making it appear as blood. They also feed on the prey once the Sapismorex kills.

Some variants appear to imitate other species in the area, like the one on the far right, which resembles a species of Sauropod (see sketch above)
