In recent experiments where hedgehogs were allowed access to poisonous toads not native to their environments, all immediately anointed themselves with scented spittle by licking the toads' poison gland
, and were unharmed.
The genus had special depressions on the side of its face thought by the investigators to have housed a poison gland
, connected by a long lateral depression above the tooth row that delivered venom to a series of long, grooved teeth on the upper jaw.
So if this theropod didn't possess a poison gland
