Onchopristis is an extinct giant (up to 26 feet long) sawfish from Africa and New Zealand. These marine creatures lived in the lower cretaceous to upper cretaceous time period. They had elongated snouts with barbed teeth that faced outward, and eyes on top of the head to easily spot predators. Similar to modern sharks and rays, Onchopristis are thought to have had electrosensors to detect prey swimming below them.
After collecting fossils as a hobby for many years growing up, Dave Douglass opened Dave's Down to Earth Rock Shop in 1970 at the age of 20 (with the help of his parents) at 1312 Chicago Avenue in Evanston, Illinois. The shop contained minerals and fossils, mostly self-collected by the Douglass family.
