Asio Horned Lizard
Scientific name: Phrynosoma asio, Long-spined Horned Lizard
This may be the largest species of horned lizard in total size and weight. Its weight in American Pewter is considerable as well. Weighing in at about four pounds it is by far our hardest piece to cast. Asio is only found in Mexico and resides on the Southern coast in or around the Acapulco region.
