Mammals produced venom even before snakes were born: Study
Africa-based researchers have found evidence of the first ever venom producing species during fossil study of a pre-mammalian reptile 'Euchambersia'. Existing 10 crore years before snakes were even born, the dog-like animal developed venom-producing features in jaws to survive the harsh African conditions. The venom could have been used for either protection or hunting, said a palaeontologist.
