RJB Posted May 23, 2015 Share Posted May 23, 2015 One whale earbone to go please. I found this in the side of a creek bank in the Scotia Sandstone formation. I forget who I donated it to? RB Link to comment Share on other sites More sharing options...

RJB Posted May 23, 2015 Share Posted May 23, 2015 Ok, talking about whales, how bout some whale barnicles? Here ya go. Not sure who I donated these to, but I don't have them anymore. These were all found in the Scotia Sandstone and Rio Dell Formations in Northern California. RB Link to comment Share on other sites More sharing options...
RJB Posted May 23, 2015 Share Posted May 23, 2015 Since im into the balanus, here is the largest one Ive ever found. This one comes from the Moonstone Formation in Northern California. RB Link to comment Share on other sites More sharing options...
PRK Posted May 23, 2015 Author Share Posted May 23, 2015 REALLY NICE RON both the whale barnacles and that giant. What ages? That giant being an edible crustacean, would've been a major meal for the costal native Americans. I thought the large balanus of mine were big but--- . I know they eat much smaller examples as I commonly find them in our local middens Do you still have that one? All beauties!!! PPK Link to comment Share on other sites More sharing options...
RJB Posted May 23, 2015 Share Posted May 23, 2015 Hi PK, yes I still have that large barnacle, that one is? I don't know, purty young, about 900,000 I think, and the others are Pliestocene. RB Link to comment Share on other sites More sharing options...
PRK Posted May 24, 2015 Author Share Posted May 24, 2015 (edited) Any ideas how those whale barnacles could get rubbed off and still be intact? Also any idea what species of whale these guys were attached too? Edited May 24, 2015 by PRK Link to comment Share on other sites More sharing options...
Al Dente Posted May 24, 2015 Share Posted May 24, 2015 Ok, talking about whales, how bout some whale barnicles? Here ya go. Not sure who I donated these to, but I don't have them anymore. These were all found in the Scotia Sandstone and Rio Dell Formations in Northern California. RB These are very nice. I hope to find one some day. Were these associated or found in different areas? These are found on humpback whales, I'm not sure if other whales have this particular species. If you look at pictures of modern ones on whales most look to be firmly embedded and not likely to rub off without being damaged. I would guess if you found a whole one it came off a dead whale.

PRK Posted May 24, 2015 Author Share Posted May 24, 2015 (edited) Ive always heard them reffered to as a generalization, "whale barnacles".The "greyish" patches on a gray whale are also barnacles. Would they be of a different variety?

Boesse Posted May 24, 2015 Share Posted May 24, 2015 (edited) Hey Ron, You donated that fossil to Sierra College, and my labmate C.H. Tsai and I published on it earlier this year in Journal of Paleontology - it's a tympanic bulla with associated posterior process of a gray whale, Eschrichtius sp., cf. E. robustus, the geochronologically earliest Eschrichtius specimen from the eastern North Pacific (slightly earlier specimens are known from the Pliocene of Japan, and we hypothesized that Eschrichtius originated in the western North Pacific during the Pliocene and dispersed to the eastern North Pacific during the early Pleistocene). EDIT: Whoops, forgot to attach the figure from our paper! Here it is. Edited May 25, 2015 by Boesse Link to comment Share on other sites More sharing options...
RJB Posted May 25, 2015 Share Posted May 25, 2015 Thanks Bobby. I donated so much stuff way back then that I cant remember where or to who. RB Link to comment Share on other sites More sharing options...
Auspex Posted May 25, 2015 Share Posted May 25, 2015 Thanks Bobby. I donated so much stuff way back then that I cant remember where or to who. RB Ron, If you post the particulars of this donation (I'm glad that Bobby has a good memory!) in the "Contributions Gallery" >LINK<, we'd be pleased to give you a little bling for your profile. Posting it according to the guidelines is a formality to recognize the importance of such amateur diligence.

PRK Posted May 27, 2015 Author Share Posted May 27, 2015 (edited) I guess one can't get any more west than this sharktooth. I had to fight the aggressive tide for this one.

ynot Posted May 27, 2015 Share Posted May 27, 2015 Hey PRK, That is a nice tooth! What type of shark is it and what is the age? Here is another one from My collection-- A pine cone from Virgin Valley Nevada 1.3 inches long, side and end views. No opal in this one... oh well. Tony Darwin said: " Man sprang from monkeys."

PRK Posted May 27, 2015 Author Share Posted May 27, 2015 (edited) Hi tony ---nice little cone. I can a-l-mo-s-t make out some color there The Astoria formation is Miocene, and the tooth is "Isurus planus" A tooth for some reason, only found in the ancient Pacific Ocean.

fossil26 Posted May 28, 2015 Share Posted May 28, 2015 Recent find of associated sperm whale ear bones from our quarry in Sharktooth Hill area of Bakersfield, ca. finding a complete whale bulla in the bonebed is very rare, but finding it with the petrosal very rare.

ynot Posted May 31, 2015 Share Posted May 31, 2015 Those are some neat Ear bones. Here are two more that are also from STH . I think that the left one is from a juvenile dolphin. Scale is a centimeter ruler. Is there a way to tell which dolphin they came from? Tony Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Boesse Posted June 1, 2015 Share Posted June 1, 2015 Both of those are kentriodontid dolphins - a group of early (and poorly understood) delphinoids at the stem of oceanic dolphins, porpoises, and white whale (beluga/narwhal). The small one I believe is the same one I identified as Platylithax robusta earlier today. The larger one is probably Liolithax kernensis, a common kentriodontid with periotics that are a bit larger and often exceed 30mm. Link to comment Share on other sites More sharing options...
