I headcanon that the Spinosaurus was left behind and died sometime during 2002-2005 (when Jurassic World was opened in 2005).

Also, the DPG List isn't really a list of species on Isla Nublar.

Maybe the Metriacanthosaurus and the Edmontosaurus were mentioned only because the other species were too much to fit onto the articles.

To be honest, this situation about the DPG thing is very mysterious.
