Ancient Wentletraps

 This is the Wentletrap Opalia varicostata, Stearns, in the gastropod family Epitoniidae. The word "Wentletrap" is borrowed from the Dutch "a winding staircase" so these are called staircase or ladder snails and this one shown here is an extinct Pliocene to Pleistocene species (less than 2 million years to about 5.3 million years). This is a gorgeous little snail and was not known from the Purisima Formation until recently!! Today, Wentletraps hang out around sea anemones, from whom they get their nourishment! #fossilprep, #Purisima, #fossilsnails, #gastropods, #beachfossils, #timelapse, #paleontology, #paleontologist, #pacificpaleontology, @pacificpaleontology,
