#FossilFriday & I am about to leave the office! But first, Chionopsis gnidia, a beautiful chionine bivalve from the Pleistocene of s. California. Common today in the Gulf of California. Worked on these eons ago as part of my dissertation... https://flic.kr/p/7Zn6fw #paleontology #CaliforniaAcademyofSciences @calacademy

#FossilFriday ! This is Uvigerina kernensis, a benthic foraminiferan from the Miocene of Kern Co., California. Holotype specimen is on the left. #paleontology @ #CaliforniaAcademyOfSciences @calacademy https://flic.kr/p/syMGVx

It's #FossilFriday ! I missed a couple, busy doing the other end of science: trying to get money. Thus, nice to be back, and with a Miocene diatom, Synedra duhemi. A pulse of diversification of producers during the Miocene, including diatoms, kelp and seagrasses, completely changed the world's oceans and climate. Important little buggers. #paleontology @ #CaliforniaAcademyOfSciences https://flic.kr/p/7xufvN

For #FossilFriday this week, we go local, really local. Here is a Pleistocene cone of the Monterey Pine (Pinus radiata) from San Francisco County, California. Yes, this is a fossil! #paleontology at the #CaliforniaAcademyOfSciences https://flic.kr/p/j3kLr4

When were alligators in Gold Gate Park's Conservatory of Flowers?
--------------------------------------------

In 1962, the alligators were hanging out in the lily pond. Steinhart Aquarium was keeping them there during their big renovation. Photo essay type article here:

I was never aware of these. Fantastic! I have to check archives to see if the #CaliforniaAcademyOfSciences had any before the 1906 fire. https://www.the-scientist.com/foundations/glass-menagerie-1863-1936-70908

A #FossilFriday vertebrate, a North American oreodont, Merycoidodon gracilis. From the Oligocene of South Dakota. These mid-sized mammals were most closely related to camels and pigs. #paleontology at the #CaliforniaAcademyOfSciences https://flic.kr/p/7v6PzU

It's #FossilFriday & and I actually get to post before the end of the day! This mackerel-like Euzaphleges longurio from the late Miocene of California, USA. Preserved in beautiful diatomaceous sediment too. #paleontology @ the #CaliforniaAcademyOfSciences https://flic.kr/p/7v6AoW

It's #FossilFriday and I'm not sure that I've seen any sponges yet on Mastodon. Thus, here is Polytholosia astoma from the upper(?) Triassic of Nevada. An important part of the post-Permian mass extinction recovery. #paleontology @ the #CaliforniaAcademyOfSciences #sponges #porifera #massExtinction #Permo-Triassic https://flic.kr/p/jB7aFo

I love being able to end a week filled with meetings with... #FossilFriday! And there is nothing better than a classic like a Late Devonian #trilobite from Morocco. Here is Odontochile; species unknown. #paleontology @ the #CaliforniaAcademyOfSciences https://flic.kr/p/7tXLzx

It's #FossilFriday & I am comfy at home in stormy n. California. Here are spines from the cidaroid sea urchin Tylocidaris bermudezi from the #Eocene of #Cuba. #paleontology @ the #CaliforniaAcademyOfSciences https://flic.kr/p/jBanwm

It's #FossilFriday better late than never! I've been stuck in Denver for 2 days trying to get home for the holiday 😩 But fossils heal all hurts right?! Here is a #Cretaceous #ammonite Chelonicera (Epicheloniceras?) irregularae from Shasta Co., #California. #paleontology @ the #CaliforniaAcademyOfSciences.

Happy #FossilFriday ! The ramshorn freshwater snail Vorticifex stewartensis from the Miocene Esmerelda Fm. of Nevada, USA. The genus is extant. #paleontology @ #CaliforniaAcademyOfSciences https://flic.kr/p/8GZ3FJ
