srjay936 Posted July 24, 2017 Share Posted July 24, 2017 (edited) Hey all, at the suggestion of others, I'm posting a photo of an ammonite fossil for assistance on species. This ammonite was unearthed by my father in 1972 in Shasta County CA. It measures 25 1/2 inches long by 20 inches tall. Any suggestions and help with its species and rarity is greatly appreciated. I get that it is not a complete specimen but hoping someone can help, Shannon Edited July 24, 2017 by srjay936 error Link to comment Share on other sites More sharing options...

Fossildude19 Posted July 24, 2017 Share Posted July 24, 2017 And pictures of the keel would help, too. The ammonite is either Triassic, or Cretaceous, in age. I wonder if @Ludwigia or @andreas might have some insight, here.

Ludwigia Posted July 24, 2017 Share Posted July 24, 2017 Could also be Jurassic, but I'm afraid that without any more detailed info on site and stratigraphy it would be hard to hazard a guess on this one.

Hmm. I didn't see Jurassic listed for Shasta County.

Wrangellian Posted July 24, 2017 Share Posted July 24, 2017 Given the size and general location I would guess something like Puzosia/Parapuzosia (Cretaceous: Turonian, my reference says). I hope you have a more specific location than 'Shasta Co', though you don't have to reveal it to the world here. 2 Link to comment Share on other sites More sharing options...
andreas Posted July 24, 2017 Share Posted July 24, 2017 Got no Triassic vibes because of preservation and matrix. My guess is Cretaceous. 1 Link to comment Share on other sites More sharing options...

I'm not at all familiar with the gelogy there, which is why I was asking for more details. I'd now agree with the others in tending toward the cretaceous, but that still leaves a lot open. 1 Greetings from the Lake of Constance.

andreas Posted July 24, 2017 Share Posted July 24, 2017 Thank you Mike for posting the plate. Just realised my link leads to the complete work not to the plate. Additionally to the plate here is the plate description. Figure Page 1, la, 2. Puzosia (Austiniceras) giganteum n. sp. Holotype and hypotype (C. A. S. Type Coll.). (1, la) Holotype. Greater diameter, 446 mm (17.5 inches) ; width of umbilicus, 146 mm; breadth of whorl, 132 mm. Locality 2245 (C. A. S.), found on Dry Creek, west of Rosewood, western Tehama County. (2) Hypotype. Found in long gulch, 1 mile north of middle fork of Cottonwood Creek, Shasta County, near horizon of Vascoceras shastense (Anderson) ; Turonian.. @Shannon: Specimen 2 was found in Shasta County. Please keep in mind that iding with pics is not more than just a good guess. regards Andreas 1 Link to comment Share on other sites More sharing options...

Wrangellian Posted July 24, 2017 Share Posted July 24, 2017 There you go, that's the publication I referred to, Plate 16 could work but I was looking at Plate 5 initially. I have the hard copy of that book! Link to comment Share on other sites More sharing options...

srjay936 Posted July 24, 2017 Author Share Posted July 24, 2017 Hey all, just checked the site and found a bunch of your responses that were not forwarded to my email. My very first post had email alerts but not this thread. Not sure what happened by thank you for the replies. I will phone and ask my dad exactly where he found the fossil and hope that helps with ID. Much of what you are saying is way out of my wheelhouse. But It looks like you all are first narrowing which period it came from then species? Is this correct. Shannon srjay936 Link to comment Share on other sites More sharing options...
srjay936 Posted July 24, 2017 Author Share Posted July 24, 2017 Wish that I could send pics of other aspects of the specimen but it is encased in plaster, which was painted over. It will be quite an undertaking to get if free of the man made matrix but I will start the project sooner than later. As I first mentioned, I wanted to know its value. You all told me you didn't do appraisals on this site but made some great recommendations to post pics and attempt to ID species first then look elsewhere to determine its collectibility and value. Thanks again Shannon srjay936 Link to comment Share on other sites More sharing options...
srjay936 Posted July 28, 2017 Author Share Posted July 28, 2017 Hey all, still trying to get some help with my ammonite ID. My father told me it came from "Little Cow Creek" in the town of Bella Vista, Shasta County. It was unearthed from the creek bank in what a Berkeley Paleo doc told him was "mudstone", not Sandstone. Hope this helps in finding the mystery of this species. Thanks, SRJ Link to comment Share on other sites More sharing options...
