Do Tadpole shrimp fuel the imagination of trilobite behavior?
Biotalker posted a topic in General Fossil Discussion
I recently watched these short videos on Nostraca tadpole shrimp/ shield shrimp. I'm sure it has been observed a million times before, but I wondered how similar the behavior of these extant critters might be to trilobites, given their convergent anatomy. Eyes on top, mouths on the underside of a shield like head, multiple similar legs/gills along its ventral surface. So to see these crustaceans maneuver, eat and remarkably molt (middle of second video), I just imagine similar behavior from trilobites, those stony motionless objects of our endless fascination.- 3 replies

Hey! I recently found this for sale, but I figured it would be good to get an ID and see what you all think before purchasing. It seems to be Notostraca, probably Lepidurus. I seller told me it’s from Yixian Formation (Jurassic), Liaoning, China.
