***********************************


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.

Looks like your camera did an excellent job of focusing on the background. :P

 

Can you try some new photos (possibly outside where the light is better)? If a fossil is good enough to be entered in the FOTM contest then it deserves some proper paparazzi photos. ;)

 

 

Cheers.

Thanks Ken

 

its the joys of using a camera phone. I’ll do some better ones when I’ve got my camera to hand.

You've got weeks till the end of the month to add some nicer photos. You'll probably not be able to edit your original post after a while but feel free to just reply with updated imagery. I'll grab the latest images when I format the contest at month's end. ;)

Not familiar with this species. Is this a common species at this site? Is this vert distinctive enough that you can tell what it is or is it a case of limited taxa at the site? Curious minds want to know, :P

Out of curiosity I went back through a couple years of the FOTM gallery, and since 01/2017, only three plants have won IFOTM. A high bar! So this month I'll submit my favorite Mazon Creek plant find so far.

 

Date of Discovery: Collected August 7, opened August 13

Scientific Name: Annularia radiata

Geologic Age and Formation: Francis Creek Shale (Pennsylvanian)

State, Province, or Region Found: Grundy Co., Illinois

Nice! I have a few Annularia stellata whorls from Mazon Creek but I've never seen any specimen this extensive. That one must have cracked a smile when you cracked it open. ;)

 

Half a month yet to go--let's see what else you all have been finding.

 

 

Cheers.

Hey guys

This one was a head scratcher in Fossil ID, and I was surprised to find very little about similar fossils. I'm especially happy about it still being held a piece of jaw, so I'll throw it in since this will likely continue to be my best find of the month!

 

Date of discovery: Sunday, August 22, 2021

Name: Hadrodus hewletti

Age and Formation: Late Cretaceous (Ozan formation)

Region: Austin (central Texas)

It may not look like much, compared to some other fossils, but it is exciting to me because I think it is a fragment of Brittlestar leg (which is relatively rare to find in the Texas Cretaceous!). Oh how I wish it was a whole one, but I'm happy with a little chunka.

 

• Date of Discovery  August 15 2021

• Scientific and/or Common Name : Brittlestar  Ophiura sp.

• Geologic Age or Geologic Formation :  Cretaceous Del Rio Formation

• State, Province, or Region Found : Central Texas, Travis County

Size: 1/8 inch  3 mm

August 21, 2021

Shimanskya postremus

Pennsylvanian, Graham formation, Finis Shale member.

Jacksboro Texas

 

I found these fragments of a cephalopod at the Lost Creek spillway site near Jacksboro Texas on August 21, 2021. Pennsylvanian, Graham formation, Finis Shale member. It includes a 90mm long section and two short phragmacones. The 8 pieces of the longer section were found adjacent to each other and fit together perfectly but the two smaller pieces were a few cm away and no points of contact could be confirmed.

 

Normally these are found there as external replacement fossils but the center section of this one is encased in a concretion. Since one side of is is broken away the inside of the shell is exposed, something I have not seen before. At first I thought it may be the body chamber because I didn't see evidence of septa or cameral deposits but then I noticed that broken pieces of the missing side as well as both smaller phragmacones have the intermediate, "fingerprint" layer found on a former Bactrites, now moved into the Coleoid subclass, order Spirulida, and renamed Shimanskya postremus.

 

 With that in mind I measured the cameral ration on other specimens found at that location and found it to be 1.3. With that information to guide me, I looked closer and found small fragments of 4 septa with the correct spacing, so it is likely to be part of the phragmacone which makes a better fit with the two associated pieces. The rarity of this species makes the associated pieces seen in the in-situ picture very likely to be part of the specimen found as articulated pieces.

I'm sure it won't be the 'forum fossil of the month' but for me it's the fossil of the month and I want to share it ... because I only made one outing to see and search for fossils during this month, and that day (August 26) I saw beautiful outcrops but only brought back a few samples, leaving on the site the more spectacular ones ( impossible to take without degrading the outcrop ).

Date of discovery: August 26th

name: tubular stromatolites, encrustation on reed stems.

age: Chattian, Oligocene

Locality: Saint-Saturnin, near Clermont-Ferrand (France)

Tubular stromatolites: These must have been reeds or aquatic herbaceous plants with stems, growing vertically and whose base was encrusted by stromatolithic precipitation. A storm must have laid down these lithified reeds. The plant matter has disappeared, but the limestone tubes remain in disorderly position.

(You can see also my trip report 'stromatolites and volcanism')

A last minute entry here (again)! 

 

I nearly thought that I wouldn't be able to finish this one in time. I had two days to prep it, and forgot on the first! :unsure: Anyway, it took approximately 2 - 3 hours to prep, and here it stands. It was found on my most recent excursion to the Leighton Fm. I really enjoy the blue-black color of the original shell. 

 

In the pictures below, the first is of it before prep. The second is of it after prep, and the third and fourth are closeups of the post-prep shell. 

 

Date of Discovery: August 29, 2021; prepped August 31, 2021. 

Scientific Name: Orbiculoidea, possibly of the species O. rugata

Geologic Age or Geologic Formation: Pridoli, Silurian; Leighton Formation. 

State, Province, or Region FoundPembroke, Washington County, Maine.

Date of Discovery: Collected August 29 or 30, 2020.  Opened August 9th, 2021

Scientific Name: Acantotelson stimpsoni

Geologic Age and Formation: Francis Creek Shale (Pennsylvanian)

State, Province, or Region Found: Grundy Co., Illinois

 

I was going through my Mazon Creek buckets and wanted to get the last of my concretions from last year's I&M Canal field trip processed before this year's event.  Had a few nice round ones left.  And, this shrimp opened in just a week... lucky day!

@JohnJ and @digit. I tried tidying that pachystropheus vert up to post some more pics but unfortunately it broke into a few pieces. I’m in the process of putting it back together.
