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 SEPTEMBER 30, 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

  1. Find a great Vertebrate Fossil or Invertebrate/Plant Fossil! Only fossils found personally by you are allowed. NO PURCHASED FOSSILS.
  2. 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.)
  3. 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.
  4. 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).
  5. 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.
  6. You must include the Common and/or Scientific Name.
  7. You must include the Geologic Age or Geologic Formation where the fossil was found.
  8. You must include the State, Province, or region where the fossil was found.
  9. 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.
  10. 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.

And where there's plant fossils you can also find insects and arthropods that will sweeten the deal. Come on in -- the water's fine! :)

Here is a cool Mazon Creek Fossil of a type of bark. I just love the detailed preservation, as well as the association of Spirorbis, ( little snail like creatures).

According to the Newest Mazon Creek Fossil Flora book, this variety is very rare. It is the first one I have found, and measures about 3 1/2 inches by 4 1/2 inches.  It was an open find. 


Date Found : Sept 3 2022

Scientific Name :  Diaphorodendron Rimosom with an association of Spirorbis

Geologic Formation : Pennsylvanian , Francis Creek Shale 

State, Region : USA, Illinois, Mazon Creek Fossil, Grundy County

This ammonite is one of an extremely few Discoscaphites iris that are nearly complete having their apertures from the famed Pinna Layer of New Jersey, noted for being a Cretaceous-Paleogene boundary site containing traces of iridium from the asteroid that hit the Earth. Combining the significance of where it was found and the near completeness of the ammonite, this is a rare find to say the least.


Date of Discovery: September 13, 2022

Scientific and/or Common Name: Discoscaphites iris

Geologic Age or Geologic Formation: Late Cretaceous Period (Late Maastrichtian), Tinton Formation, Pinna Layer

State, Province, or Region Found: New Jersey

I take advantage of this section to introduce you to this crab which I have just finished preparing. I decided not to go any further so as not to take any more risk.
The 41 mm carapace makes it a huge specimen.

You unfortunately won't see the pictures when it was discovered because I was so excited I forgot to take the pictures...



• Date of Discovery :  September , 15 , 2022

• Scientific  Name : Chlinocephalus demissifrons

• Geologic Age : Pliocene

• France , Languedoc-Roussilon



Results after stabilization:





to give an idea of the size as well as a different view

Thought it's time I give FotM a try, though this month looks pretty invertebrate heavy! I found this crinoid crown on my first trip with the PSoA. The ID for this guy is still a little iffy.

• Date of Discovery  (month, day, year): September 24th, 2022

• Scientific and/or Common Name: Ethelocrinus magister crown with parts of the arms, stem, and small spines

• Geologic Age or Geologic Formation: Pennsylvanian, Adams Branch Limestone (Canyon Group)

• State, Province, or Region Found: Brownwood Area, TX











GL everyone!
