日前美国加州大学伯克利分校的古生物学家Mark Goodwin和蒙大拿大学的Jack Horner根据一件珍贵三角龙幼年个体的化石进行了关于三角龙和其他恐龙生长模式的研究。幼年的三角龙化石上保存有角和颈盾,证明其角和颈盾除了用于求偶炫耀斗争之外还有其他功用,比如视觉信息交流的标志。同时,其头骨表面的沟槽是用来容纳血管的,成年三角龙头颅表面覆盖的层层加厚的角质 Recently, Mark Goodwin, a paleontologist at the University of California at Berkeley, and Jack Horner of the University of Montana conducted a study on triceratops and other dinosaur growth patterns based on the fossils of a rare triceratops individual. Juvenile Triceratops fossils preserve horns and neck shields, proving that their horns and neck shields have other functions besides courtship to show off their struggles, such as the sign of visual information exchange. At the same time, the groove on the surface of the skull is used to accommodate the blood vessels, the horniness of the trichosantal cranial surface covered by layers of thick cutin
