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

Found what looks like to me like a tail of some crustacean in Saltwick Bay a few years ago. It's about 3 inches long, and the surface detail is incredibly well preserved. Was wondering if anyone has found anything similar, or knows what kind of crustacean it could have come from?

Oxford clay, Peterborough Member, Jurassic, Callovian, near Yaxley in Cambridgeshire. I spent the morning getting muddy in wet clay, and found this. I think it might be part of a hybodont spine, or other ornate fish spine. I've collected a fragment of hybodont spine from this site before. The surface does seem to be enamel, and the shape is slightly curved. Any assistance greatly appreciated.

I run across these guys frequently in the Mississippian Redwall Limestones around Arizona's Verde Valley. They are generally accompanied by lots of Crinoids and solitary Rugose Corals. They're always this oval shape with segmented structure. They look like an isopod, to me, but could be some other crustacean. Any help out there for the identification of these "bugs?"

I didn't get out hunting much last year, still working on figuring out how to research and find spots, but a friend of mine invited me out to do some collecting at one of his spots up in Washington State. I took some family with me and we went out over the Winter break in mid December. Pretty cold but beautiful! We're mainly looking for concretions weathered out of the formation, but occasionally you find Callianopsis claws loose in the formation, usually very brittle and in poor condition. Lots of mollusks to be found as well as crustacean

Hello all, I found the following (possible) Hoploparia sp. tail, abdomen section, and partial claw/arm on a recent trip in NJ. I haven't seen too many of these posted so I thought I would share. I also included a video to show how much is exposed on each side. Thanks for viewing. VID_178761207_233632_277.mp4

My mom found this on the beach in Wilmington North Carolina while hunting for shells. I've done some image searches online and my best guess is that its a dactylus or pincher from some type of large crustacean or crab. The piece is approximately 6 inches long. My parents thought it could be a jaw bone of some type of sea creature. Any help or best guesses would be appreciated!

Hi Everyone, Found this at the NSR last weekend. I would really like to remove some of the grey matrix but that is beyond my skill set. Do not wan to ruin any of it. So, how would I go about stabilizing it? I use clear Elmers glue for the bones and some ammonites but not sure about soaking this in that mixture. Any help is appreciated.

Can anyone ID this please? Found in Surrey, England on farmland/woodland. Possibly the underside of a crab? Thanks

Out of the countless New Jersey cretaceous crab claws I've seen and found this has to be one of the strangest claw partials yet. Seems to be an ornamented shell as apposed to the smooth claw textures that are typically found. Definitely a very interesting piece, anyone have any ideas on a possible species or if any ornamental crabs have found in nj cretaceous, or any other new jersey cretaceous hunters ever come across one similar? Definitely a head scratcher

Hello all! I have two weird ones I found in Monmouh County New Jersey (Cretaceous). The crustacean is interesting to me because I was initially thinking Hoploparia gabbi however, it is over twice as wide as any other specimen I have found (comparison pictures below). It was suggested that another lobster, Linuparus, could be an option but we really weren't sure. This measures 2.5 inches The other one measures .75 inches and has one cutting edge and an oval base. What is holding me back from saying Xiphactinus is the fact that it isn't fluted and only has one cutting edg

I recently found this coral (I'm calling it Platycyathus vancouverensis until I learn otherwise) at my local site, Mt. Tzuhalem (Haslam Fm, Santonian), with apparently a cluster of pellets inside the 'cup' formed by the septa on the top side. Usually only the rounder bottom side is exposed when I find these corals, as the septa tend to hold onto their matrix. I'll try for better pics if needed, but it's tough! Note that they are all quite small - less than a millimeter. Another specimen that I've had for longer, with septa exposed (more or less), seems to have less obvious bump
