Over time, wind and waves grind and chew that plastic trash into tiny bits of what's called " microplastic" —which happen to be about the same size and shape as the micro algae that filter feeders like oysters snack on.

而随着时间的推移，风和海浪的侵蚀及不断冲刷会将这些塑料垃圾变成极小的微塑料—而这些微塑料的大小及形状又恰巧和牡蛎等滤食动物食用的微型海藻相同。

That's where the name " Atopodentatus" comes from - it literally means " unusual teeth." Its peculiar dentition looked like some pterosaurs that are suspected to have been filter feeders and whose teeth would've been too fragile to grasp or crunch prey.
