Different sized grains of dirt travel at different speeds.
不同尺寸的泥土颗粒在水流中的速度不同。
Fast moving water means little grains travel very quickly, bigger grains lag behind.
快速流动的水意味着小颗粒移动得非常快，大颗粒被甩在后面。
So when they found these dinosaurs they were completely encased in the same sized grain, and that tells us that these animals were washed into their position.
当他们找到这些恐龙时，它们是完全一样大小的颗粒，那告诉我们这些动物是被冲到它们的位置的。
But the flash flood raised new questions.
