Final answer:
Characteristic features of stegosaurids include their distinctive tail spikes, known as 'thagomizers,' used likely for defense.
Step-by-step explanation:
Characteristic features of stegosaurids include tail spikes.The characteristic features of stegosaurids include tail spikes and clawed hands. These dinosaurs had long, bony spikes at the end of their tails, which were likely used for defense against predators. They also had clawed hands that could be used for digging or foraging.
Stegosaurids were a group of dinosaurs known for their distinctive body structure. These dinosaurs had short forelimbs and relatively long hind limbs, which together with a strong, spiked tail enabled them to maintain a stable posture while standing. The signature tail spikes, known as 'thagomizers', served likely as a defense mechanism against predators. Contrary to some popular portrayals, their skulls were low and broad, not long-snouted, and their hands, though featuring claws, were not their defining characteristic. The long, horizontal plates along their backs further separate them from other dinosaur groups.
