digit Posted June 29, 2020 Share Posted June 29, 2020 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 JULY 31, 2020 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.

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.)

minnbuckeye Posted July 13, 2020 Share Posted July 13, 2020 Is it my computer or has no one entered this month's competition????????????????????????????????? So, I might as well throw one into the ring in hope other entries do not show up, or at least for the invertebrate category!! Then I may have a chance at victory. LOL My find was on 6/15/2020. As can be seen, prep was necessary to bring out the trilobite's detail.Prep was finished on 7/10/2020. I do have to give @RandyBpartial credit for talking me into showing him this site. And I must heavily credit @isotelus for the wonderful prep! The trilobite is 1.75 inches long. This is Thaleops ovatum Platteville Formation Ordovician Grant County, Wisconsin 28 Link to comment Share on other sites More sharing options...

PrehistoricWonders Posted July 13, 2020 Share Posted July 13, 2020 Wow that’s an amazing specimen!!! I’m planning on entering a string of three associated shark vertebrae, from the chandler bridge formation, but I don’t know what type of shark they come from and it seems virtually impossible to correctly I.D shark verts, is it still eligible?

Yup. You simply need to be identify it as well as can be done. With shark vertebrae it is generally not possible to get a very tight ID unless there is a limited diversity of possible choices in the formation. I do believe that the number, size, shape and placement of the oval holes on the edge of the verts can be diagnostic at least to family (lamnid or carcharhinid). Back in your trip report topic you should tag some members who might be able to help with this--offhand I'm thinking that al dente, MarcoSr and sixgill pete might be a good start. Cheers. -Ken Link to comment Share on other sites More sharing options...

gieserguy Posted July 14, 2020 Share Posted July 14, 2020 Hey all! My roommate and I recently went on a little fossil hunting in Oglesby, IL and found these lovely little shark teeth. I certainly love the heck out of ‘em and they seemed to get a very positive response in their ID thread, so I figured why not throw them into this month’s mix Both teeth were found in close proximity (about a foot away) on the same stone, on the same face, so I will consider them associated/from the same animal. Found July 12, 2020 Two associated teeth of Heslerodus sp. Bond Formation, LaSalle Limestone Member Carboniferous, Pennsylvanian Oglesby, IL Tooth 1 Tooth 2 8 Link to comment Share on other sites More sharing options...

JohnJ Posted July 14, 2020 Share Posted July 14, 2020 @gieserguy Do you have an image showing both of them in the same rock? The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

That was actually a major oversight on my part. The rock was really big (almost too heavy to tilt) so I broke it apart to lighten the load, and in my excitement I forgot to take a picture of the whole rock. I did manage to take a couple closer photos of the teeth that can just barely prove that they were on the same rock. I apologize this in the only proof I have that they’re associated This is tooth 2. The V shaped crack on the left that opens up to a small crinoid section is what you can use to connect the two pictures. In the very top right of this picture of tooth 1, you can see the V shapes crack opening in the same orientation towards the crinoid piece. Again, I’m really sorry I don’t have any better pictures but I was excited and got too ahead of myself :/ (also, fun little sidebar: you can see chisel marks around tooth 1 in the second photo from someone who had tried to extract the tooth before, but ultimately gave up!) 1 Link to comment Share on other sites More sharing options...
gieserguy Posted July 14, 2020 Share Posted July 14, 2020 Now that I’m looking closer at these photos, tooth 2 might actually be in the second photo. It isn’t visible, considering the tiny size of the teeth, but tooth 2 would presumably be at somewhere about the red circle. 1 Link to comment Share on other sites More sharing options...

FossilsandScience Posted July 15, 2020 Share Posted July 15, 2020 I was super excited with this find, as entelodont material is super rare! There is a large jaw section with two premolars and two molars. Another piece of the jaw section has a canine and a premolar. Those two jaw sections connect, which one of the photos below shows. There was also a fully rooted tooth found! The jaw section with the canine and premolar was laying right on top of the sediment, while the larger jaw section had only a small part of the end exposed. The fully rooted tooth was found in the matrix with the jaw! This fossil was found on July 3rd, 2020. It is a lower jaw section from a juvenile Archaeotherium mortoni, which is a species of entelodont. It was found in the White River Formation, about 30 million years old in Wyoming. Here is the larger jaw section with the premolars and molars: Here is the fully rooted tooth!: This is how the two jaw sections connect: 12 Link to comment Share on other sites More sharing options...
