Spinosaurus was pretty cool, but it was a specialist predator. Used to hunting fish in rivers and coastlines, the Spinosaurus was put at a major disadvantage when declining sea levels turned its watery environment into forests and deserts. This meant that it had to hunt land animals instead of fish as a source of food, which it was not adept at due to its very large size and semi-clumsiness on land. The species was eliminated as a result, unable to adapt quickly enough to its changing environment.

This is what is happening with many specialist species today, as humans expand into their habitat and drastically alter its environment. Generalist species, like crows and raccoons, on the other hand, are thriving because of all the consumables and trash that humans leave out for them.
