digit Posted November 30, 2022 Share Posted November 30, 2022 REMINDER: PLEASE carefully read ALL of the rules below. Make sure you include all the required information, IN THE REQUESTED FORMAT (below) when you submit your fossil! If you have a question about a possible entry, please send me a PM. Please pay special attention to Rule #5: Before and After Preparation Photos must be submitted for prepped specimens NOT found during the Month of the Contest. In addition to keeping the contest fair, this new qualification will encourage better documentation of our spectacular past finds. Entries will be taken until 11:59:00 PM EDT on DECEMBER 31, 2022 Any fossil submitted after that time, even if the topic is still open, will be deemed ineligible! Only entries posted with CLEAR photos and that meet the other guidelines will be placed into the Poll. Photos of the winning specimens may be posted to TFF's Facebook page. Please let us know if you have any questions, and thanks for sharing more of your fossils and research this month. Shortly after the end of the Month, separate Polls will be created for the Vertebrate and Invertebrate/Plant Find of the Month. In addition to the fun of a contest, we also want to learn more about the fossils. Tell us more about your fossil, and why you think it is worthy of the honor. To view the Winning Fossils from past contests visit the Find Of The Month Winner's Gallery. Now, go find your fossil, do your research, and make an entry! Best of success to all, and good hunting! *********************************** Rules for The Fossil Forum's Vertebrate and Invertebrate/Plant Find of the Month Contests Find a great Vertebrate Fossil or Invertebrate/Plant Fossil! Only fossils found personally by you are allowed. NO PURCHASED FOSSILS. Post your entry in the Find of the Month topic. Use a separate post for each entry. (Only two entries per member per contest category.) Your fossil must have been found during the Month of the Contest, or Significant Preparation * of your fossil must have been completed during the Month of the Contest. You must include the Date of Discovery (when found in the contest month); or the Date of Preparation Completion and Date of Discovery (if not found in the contest month). Before and After Preparation photos must be submitted for prepped specimens not found during the Month of the Contest. Please make sure you arrange for photos if someone else is preparing your fossil find and completes the prep requirements in the contest month. You must include the Common and/or Scientific Name. You must include the Geologic Age or Geologic Formation where the fossil was found. You must include the State, Province, or region where the fossil was found. You must include CLEAR, cropped, well-lit images (maximum 4 images). If you are proud enough of your fossil to submit it for FOTM, spend some time to take good photos to show off your fossil. Play fair and honest. No bought fossils. No false claims. * Significant Preparation = Substantial work to reveal and/or repair important diagnostic features, resulting in a dramatic change in the look of the fossil. The qualification of Significant Preparation is decided at the discretion of staff. Any doubts as to the eligibility of the entry will be discussed directly with the entrant. ******* Please use the following format for the required information: ******* • Date of Discovery (month, day, year) • Scientific and/or Common Name • Geologic Age or Geologic Formation • State, Province, or Region Found • Photos of Find (Please limit to 4 clear, cropped, and well-lit images.) (If prepped, before and after photos are required, please.) Link to comment Share on other sites More sharing options...
Dimitris Posted December 13, 2022 Share Posted December 13, 2022 Thought to start the month's entry. Last month we went to the East Rhodopes, a mountain covering most of SE and S Bulgaria. After splitting some stones under a cliff, a friend starting shouting and he said that I had found an amazing echinoid. Anyway, I could only see a small spot out of the rock and some numulites here and there but nothing interesting. He knew though, having visited the place numerous times. This Friday, I started cleaning with KOH and something interesting started showing. I finalized it with alum oxide blasting. Overall size, 2.4cm or almost an inch. First picture, after having started KOH treatment, second is a close-up and last overall onto matrix. Two more experienced friends suggested that the part missing is pathological. Edit: Second picture is with KOH, I uploaded them in wrong order. Date of Discovery (8th November 2022) • Rumphia sp • Oligocene • Kardzhali, Bulgaria 11 Link to comment Share on other sites More sharing options...

Pseudolioceras lythense ammonites are found in the Bifons Zone in the Upper Lias, Lower Jurassic (merely a swap of directions which I can easily tweak). Always nice to have the best information here on the forum as these topics are archived and available to view for years....

digit Posted December 22, 2022 Author Share Posted December 22, 2022 There's a tooth that means business--glad I'll never be on the receiving end of that one (unless I catch my finger on it while digging for fossils which I've done and drawn blood). Just a week or so left for this FOTM contest which wraps up 2022. Surely, we're not all holiday shopping and someone else out there has some entries for this month. Great entries so far but what else have you got? Cheers. -Ken 3 Link to comment Share on other sites More sharing options...
Fin Lover Posted December 22, 2022 Share Posted December 22, 2022 (edited) Since you are asking for more, here you go: Date of Discovery: Dec. 17, 2022 Scientific and/or Common Name: Carcharoides catticus Geologic Age or Geologic Formation: Oligocene, Chandler Bridge Formation State, Province, or Region Found: Summerville, SC These are apparently uncommon to rare and also delicate, so finding one in this condition is a treat (or, according to a post from @siteseer the day before I found this, "a collector's dream"). Once I cleaned the creek scum off, it was a beautiful silver color.

Mikrogeophagus Posted December 22, 2022 Share Posted December 22, 2022 (edited) It's a longshot, but here's my personal fossil of the month. I revisited an old Pawpaw site (where the ammonite in my pfp came from). I was worried it would be developed while I was gone, but it seems construction was slow. Not only that, but the site is 100x more productive since then! There were ammonites and crustacean bits everywhere. This specimen is my most detailed crab carapace from the hunt. I believe it's Xanthosia wintoni, but I have also seen the name Feldmannia wintoni and others thrown around as well. The carapace is only 15mm by 9mm, yet it is still extremely detailed. The face is especially well preserved. I think picking up blue crab from the market earlier that day gave me good luck Date of Discovery: December 21, 2022 Scientific and/or Common name: Feldmannia wintoni carapace Geological Age and Formation: Pawpaw, Upper Albian of the Cretaceous Location: Tarrant County, TX Edited December 22, 2022 by EPIKLULSXDDDDD Fixed genus name, thanks for the info y'all 1 19 Link to comment Share on other sites More sharing options...

FossilDAWG Posted December 22, 2022 Share Posted December 22, 2022 The species was originally assigned to Xanthosia, but it was revised several years ago and assigned to the (then) new genus Feldmannia, Very nice specimen! Don 1 Link to comment Share on other sites More sharing options...

mamlambo Posted December 27, 2022 Share Posted December 27, 2022 I finally found a fossil penguin in Aug this year and finished prepping it a few days ago. It's really well articulated and most importantly, it has the very diagnostic tarsometatarsus (TMT) bone preserved. The TMT was hiding underneath the tibiatarsus so it was very lucky to have it at all as it should by all rights have been outside of the concretion. A small section of the skull is also present. I used an air scribe and vinegar to prep the fossil. I'll be donating it to a New Zealand museum so it can be studied further. I'm not sure what species of penguin it is at this point. Here is a time-lapse of the prep: https://youtu.be/eBc82mnlZBU • Date of Discovery (month, day, year) Aug 2022, finished prep Dec 2022 • Scientific and/or Common Name: unknown fossil penguin (probably late Miocene in age) • Geologic Age or Geologic Formation: I suspect the Greta formation • State, Province, or Region Found: Canterbury, New Zealand As found on the beach Well articulated fossil penguin. The furcula (wish-bone) is broken and happened before it was fossilized. The tarsometarsus on the back of the concretion - it's the most diagnostic bone on a penguin and can help place it in the right spot in the penguin family tree.
