Wouldn't life be so much more exciting if they were still here. You wouldn't need burglar alarm if you had one of them in your garden.

most of these creatures can still be observed at your local walmart.
Stethacanthus
An extinct genus of prehistoric sharks, Stethacanthus or ‘chest spike,” was about 6 feet long with a strange looking back growth on males. This small protrusion or ‘ironing board,’ could have been used to frighten larger predators.
