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 AUGUST 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

  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.

• 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.)

I start this subject with this murex of a respectable size of 65 mm that I found a few days ago despite the heat wave!
It is the most beautiful specimen of this species that I have been allowed to observe. The photos are a summary of the moment of its discovery until the final result.



• Date of Discovery :  August , 02 , 2022

• Scientific  Name : Hexaplex (Trunculariopsis) trunculus conglobatus ( Michelotti, 1841) - (cf. MNHN) 

• Geologic Age : Pliocene

• France , Languedoc-Roussilon


The day of the discovery on the site:

I'll submit this concretion that opened yesterday. Acanthotelson is one of the more common Mazon Creek shrimp, but I've never found two in one concretion before!


Date of Discovery: Collected sometime in 2022, opened August 17

Geologic Age or Geologic Formation: Francis Creek Shale (Middle Pennsylvanian)

State, Province, or Region Found: Grundy County, Illinois

I’ll go ahead and submit this very intriguing trilobite I found today.

Date of discovery: August 19, 2022

Scientific name: Monodechenella macrocephala

Geologic age or geologic formation: Middle Devonian, Hamilton Group, Moscow Formation, Windom Member

State, province, or region found: Deep Springs Road locality in Earlville, New York. 

Officially speaking, Monodechenella macrocephala is not supposed to be in the Windom Member of the Moscow Formation. This is the only specimen I have ever seen or heard of from the Windom Shale, making it quite a special find!

Bringing Fossils to Life

Date of Discovery: August 18, 2022

Scientific Name: Striacoceras typum var. beta

Geologic Age or Geologic Formation: Middle Devonian, late Givetian, Hamilton Group, Mahantango Formation

State, province, or region found: Seven Stars, PA

These two orthocerid nautiloids were found right up against each other, facing opposite directions. They both preserve the end of the body chamber, and in the smaller one several chambers of the phragmocone. It is the sheer size of these specimens that makes them so special, especially when remembering that these nautiloids lived alongside Dipleura, a giant predatory trilobite. This provides evidence that the two predators relied on different food sources, both of them being very successful at this particular site. These are also the first fossils I successfully chiseled out of the rock.


The two specimens fully excavated.


The smaller specimen in situ.


The larger specimen in situ, with the imprint of the smaller specimen visible.

please add them! The point of the contest I think isn't necessarily to see "who will win", but rather to see all the awesome fossils found each month proudly showcased - with a friendly competition as the cherry on top :popcorn:
