Was triceratops skin bumpy

it was once believed that triceratops skin was your typical lizard type skin with scales, so bumpy as a result of the interlocking layers of scales. however recent evidence has shown that triceratops may have had rows of bristles along its back, somewhat like a porcupine

Triceratops are dinosaurs. They are extinct. We have theories that they were reptiles, so it is generally accepted that they had scales for skin, like today's reptiles.
