Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct

What is the group with the most extinctions?
This is an interesting question and not one that is easily answered. In terms of the entire history of life on earth the groups of individual species that have been around the longest would have experienced the most extinctions. The more complex the animal the fewer organisms produced and therefore the fewer species available for extinction. This makes various unicelluar organisms (animal, plant and bacterial) subject to the most extinctions. Even though several mass extinctions have occurred, the focus is primarily on the larger identifiable organisms of the time, (Dinosaurs for example), especially those that have a fossil record proving they existed. This places the focus on complex plants and animals. Focus is often on man caused extinctions as well...which are, on the whole, a very small number in the grand scheme of the history of life on Earth. The primary concept to remember is that: Extinction is the rule, NOT the exception.
