A dinosaur creature exiled and subsequently played using Intrepid Paleontologist enters the battlefield with a finality counter on it. While Skullspore Nexus is on the field, whenever one or more creatures are destroyed, a fungus dinosaur token is created with power and toughness equal to the total power of the destroyed creatuers. If a dinosaur that has been played using the exile ability of Interpid Paleontologist is destroyed, it does not trigger the ability of Skullspore Nexus. SkullSpore Nexus makes no mention of finality counters, and the dinosaur played by the ability of Intrepid Paloentologist is not a token; it is the original creature, but with a finality counter. Therefore, the destrution of a dinosaur played with the ability of Intrepid Paleontologist should trigger the token creation of Skullspore Nexus.
