@revalyt I spiced your SCP profile for this beast up a bit:
SCP-4392 “Human Theropod”
Object class: Euclid

Description
SCP-4392 is a mammal with the anatomy similar to a large prehistoric theropod. SCP-4392 is stated to have very tough and durable “skin” whereas areas that appear to have “clothes” are very thick and leathery. It’s skin resembles clothing that of a crimson shirt and black jeans in a pattern similar to the southern tamandua. The reason behind this adaptation is unknown. SCP-4392 stands at 11 1/2 feet, quadruped being 7 1/4 feet, its length from start of skull to tail tip is 40 feet, weighing 11 tons (22000 lbs). It is also unknown why this SCP has adapted a quadruped stance but it is speculated to help it get into tough spaces or for more mobility. SCP-4392 possesses quills near the base of the head resembling hair, these quills allow SCP-4392 to sense differences in the atmosphere. It’s been documented that this SCP is in a constant state of high awareness and has been seen tilting its head to even the slightest sounds, the quietest being the drop of a clipboard. It’s vocal range consists of clicks and growls but it rarely ever roars, it’s real roar sounding like a raspy high-pitched scream. It has also been documented that it is rather intelligent, watching staff members through the glass intently and knowing exactly when feeding time occurs. It is to be fed 3 times a week (Sunday, Tuesday, Thursday) at exactly 12 PM, preferably live cattle.

Special Containment Procedures
SCP-4392 is to be kept in a 200 x 200 x 30 room, formed to look like the wild with a small pond for it to drink from and a skylight made of bulletproof glass a foot thick. In case of a breach it is to be blocked off by a strong heat source as subdued carefully with tranquilizers.

Note: though not proven, it’s speculated that it is intelligent enough to release other SCPs. Do not let it breach.
