    Chione californiensis, Late Pleistocene, Bahia de los Angeles, Baja California. I collected these specimens more than 10 years ago, when Bahia was still an isolated paradise. One of the world's most beautiful vistas, I swear. The specimens here are much larger than conspecifics now found in the Gulf.

      My ignorant question: What's the grid scale? Centimeters? Millimeters?

      Centimeters ron. One of the interesting things is that the same species were much larger here as fossils than they are today in the same area.

      Any educated guesses about why they used to be bigger/got smaller? Are there congeners elsewhere that are bigger now?

      Y'all used to have a mock-up coal swamp with a millipede that gave me the willies. And I'm not even all that phobic about real millipedes like the ones the EB Vivarium has. Too many legs plus natural 'ludes, though, yikes.

      Well, I think that that the waters were more productive; basically more food around. It was also warmer, since it was a warm interglacial. The fossil deposit is several hundred meters inland, so that gives you some idea of how much higher the sea level was. Sadly, the little ravine in which the deposit is exposed had become a garbage dump by the time we visited. It's about a mile out of town, therefore convenient. Of course, said garbage dump is located on one of the most stunning beaches in Baja. Sigh.
