![]() | Paleontologists announced the discovery of an "exceptionally well preserved" ancient creature near the eastern shore of Lake Simcoe in southern Ontario. It was found in a stone quarry that scientists have dubbed the "Paleo Pompeii." Named Tomlinsonus dimitrii, the specimen is part of an extinct group of arthropods known as marrellomorphs that lived approximately 450 mya, during the Ordovician period. Researchers discovered the bizarre arthropod last summer during a formal excavation of an active quarry. Similar to the Burgess Shale, the Lake Simcoe quarry was once submerged and part of a shallow ancient tropical marine sea. |
