霍普金：一些较小的物种，如棘龙和细角龙，可能会在地下挖洞并冬眠。

So far, Druckenmiller and his team have dug up species from seven different dino families: from big duck-billed dinos, ceretopsians, and tyrannosaurs to smaller thescelosaurs, leptoceratops, dromaeosaurs, and troodontids.

迄今为止，Druckenmiller 和他团队已经挖掘出7类恐龙：从大型鸭嘴恐龙、角龙、霸王龙到较小的奇异龙、纤角龙、驰龙和伤齿龙等。

It's possible that the speedier juveniles hunted small herbivores, like the roughly 2-meter Leptoceratops or the 4.5-meter Pachycephalosaurus--while bite marks on fossils tell us the adults ate big game, such as Triceratops.

速度更快的幼龙可能会捕食小型食草动物，例如大约 2 米长的 Leptoceratops 或 4.5 米长的 Pachycephalosaurus——而化石上的咬痕告诉我们成年龙吃大型猎物，例如三角龙。
