玻利维亚有16 600个化石化的恐龙脚印, 揭示了在史前湖附近迁徙的大型类动物的群落, 并有罕见的行为证据。 16,600 fossilized dinosaur footprints in Bolivia reveal herds of large theropods migrating near a prehistoric lake, with rare behavioral evidence.

玻利维亚Toro Toro地区的恐龙脚印是大约6600万年前的化石,它揭示了史无前例的对热带动物行为的洞察力,有16,600条足迹 — — 创历史最高记录 — — 保存在古老湖床沉积物中。 Fossilized dinosaur footprints in Bolivia’s Toro Toro region, dating to around 66 million years ago, reveal unprecedented insights into theropod behavior, with 16,600 tracks—the highest number ever recorded—preserved in ancient lakebed sediment. 大量两条腿的恐龙(包括暴龙的亲属)留下的指纹显示有行走、跑步和试图游泳的证据,表明不同尺寸的牛群将该地区用作淡水沿岸附近的移徙走廊。 The prints, left by large, two-legged dinosaurs including relatives of Tyrannosaurus rex, show evidence of walking, running, and attempted swimming, suggesting herds of varying sizes used the area as a migratory corridor near a freshwater shoreline. 尽管铁轨、化石骨、牙齿和鸡蛋很多,但几乎都不存在,原因可能是该场地作为临时通道而不是永久栖息地所起的作用。 Despite the abundance of tracks, fossil bones, teeth, and eggs are nearly absent, possibly due to the site’s role as a temporary pathway rather than a permanent habitat. 人类活动,包括农耕和道路建设,对保护工作构成威胁,但正在进行的研究继续发现新的轨道,提供了罕见的行为记录,与骨骼遗骸不相配。 Human activity, including farming and road construction, has threatened preservation, but ongoing research continues to uncover new tracks, offering a rare behavioral record unmatched by skeletal remains.
