Hey Gang, Going thru another garage box of old stuff and was wondering if you all can tell me if these 3 are all different Mitra species. Slight variability in the exterior ornamentation and spire heights and overall shell shape seem different. Maybe Mitra lineolata for the taller spired version on the very right? Spoil finds from APAC Sarasota Florida..Probably Tamiami Fm. Plio-Pleistocene. @MikeR Thanks for any help. Regards, Chris

By any chance does anyone recognize these little orb/circular structures/features in some of the damaged Vermicularia tubes in these shots? Not sure if they might be simply immature bivalves or something else? I pried out a few of them and I'm no wiser as they are so small and I dont see any real features/markings under magnification... The two that I pried out are approx .5mm wide but the others still in the tubes are a bit bigger. The 2nd and third frames in the 2nd photo makes them look like something that could be a small echinoid with star shaped markings but that might be deceiving. they actually look more like absolutely smooth micro PVC endcaps, not spheres/orbs. In my other recent Garage finds thread Adam had a good question about operculums and I dont even know if they had one or not...So if you all have any insight I'd love to hear/know.. Thanks for the help. Regards, Chris
