All true.  Nevertheless, the giant anteater can use its massive
foreclaws as a weapon when confronted, typically by adopting a
bipedal/tripodal posture.  Jaguars are known to fall afoul of an
anteater's claws.

To return to dinosaurs, this is how I imagine therizinosaurs used
their foreclaws.  If you can't be fast, be formidable.
