Goody Posted May 16, 2019 Share Posted May 16, 2019 Hello, SF Bay Area native here, totally new to this forum and to collecting anything other than rocks found on the beach. On one excursion just after a stormy high tide on a private access beach south of Pomponio, I came across these two cetacean(?) fossils(?) washed ashore, each of which weigh ~5+ lbs. Any further info anybody could offer would be great! Link to post Share on other sites

abyssunder Posted May 30, 2019 Share Posted May 30, 2019 These give me a geological vibe, but please wait other opinions. Link to post Share on other sites
DPS Ammonite Posted May 30, 2019 Share Posted May 30, 2019 See if the white rock is limestone by seeing if it fizzes in acid. Both Franciscan limestone and marble occur nearby and contain no macrofossils. In fact, UC Santa Cruz has at least two caves in marble. Link to post Share on other sites
