Both horned dinosaurs had a giant bony frill that rose up behind the head, but <em>Torosaurus</em>&rsquo; frill was much longer and was adorned with giant holes that were covered by a thin layer of protein called keratin. Yet <em>Triceratops</em> and <em>Torosaurus</em> may have been more alike than scientists realized: New research suggests that the two animals were actually the same species, with <em>Torosaurus</em> being the adult version of <em>Triceratops</em>.</p>
