Pterodactyl Posted February 5, 2016 Share Posted February 5, 2016 Hey all. I heard you could find some really nice fossilized sand dollars in or near San-Francisco. Does anyone know where the site might be? "Welcome...To Jurassic Park!" -Richard Attenborough Link to comment Share on other sites More sharing options...
DPS Ammonite Posted February 5, 2016 Share Posted February 5, 2016 They are in the Pliocene/Pleistocene Merced Formation in Daly City which is just south of San Francisco. Look in the sea cliffs from John Daly Blvd. on the north to about 1 mile to the south. There are lots of shells and some pinecones. Avoid high tide, watch for waves and landslides. See this publication for more info.http://www.geologictrips.com/sf/sfttff.pdf sfttff.pdf 2 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere. Link to comment Share on other sites More sharing options...

However, the sand dollars are difficult to clean because it's hard to see where the rock ends and the sand dollar surface begins. Like other prep people of the time, he take home chunks with sand dollars showing on the side and grind down to about the surface and then polish the surface. I assume he applied a hardener to keep the sand dollar from cracking/chipping. I remember seeing the polished ones from time to time at shows - haven't seen one in a while.
