Therizinosaurs were some of the true freaks of the dinosaur world. I mean that in the nicest possible way for something that looked like the sick offspring of a giant chicken and Freddie Kruger. Perhaps the weirdest things about them were these long, scythe-like claws, that although may have seemed deadly, probably weren’t unless you were a particularly scrummy looking piece of foliage. That’s right, these cousins of tyrannosaurs and other theropods used their wicked sickle-claws for trimming hedges for food.
