I revived the Titanis, so I put back the flesh and feathers and now he is fine.
Some parts of the body are missing, like the head and beak, so now it looks more like a mammal. Also the arm bone were gone so now the keel has feathers. He is now very happy in the laboratory, but it is still a carnivore and it has no beak, so we still need to feed the animal. @Rudi10006 @cs893276
