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.

 

******* Please use the following format for the required information: *******

Date of Discovery

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.)

Again starting FOTM entries :D!

Its nothing very special nor rare, but I have not found such an intimate association of this type of predator and prey so far:

 

Date of Discovery: 10/01/2019

Name: Naticid gastropod Cochlis sp., arc clam Striarca lactea with naticid drill hole.

Age and Formation: Langhian, Miocene / "Florianer Schichten", Styrian basin, Eastern Alps

Locality: Höllerkogel-10, St. Josef, Styria, Austria

I don´t suggest that this particular naticid gastropod has drilled this particular arc clam nearby. But its still nice to have prey and predator within a few millimeters in the same specimen. Arrangement of fossils is not totally optimal, but that would be over the top :D; I am still very satisfied with the specimen :).

"Preparation" was mostly done with sharpened, wooden tooth picks, no stabilization necessary. Specimen is photographed damp, but not wet.

And now eagerly waiting for the next entries, I like this topic very much, always exciting and educational!

Good start, Franz. That is a particularly nice association piece, even if we don't know for sure that that particular snail drilled that hole! (Do you recall nala's 'fossil associations' thread?)

I felt this was worth posting as it is only the second I have come across, and it's a decent size. Originally I only took one half due to all my equipment being so heavy and not having a third hand. After returning the next day and grabbing the other split half, along with some minimal cleaning I definitely think it was worth going back. 

 

Date of Discovery: October 14, 2019

Scientific and/or Common Name: Aviculopecten sp. Pectinid Bivalve

Age: Mississippian

Province, or Region Found: Henry County, Missouri, USA.

Three weeks into October, and only 3 entries... :o:headscratch:So I will upload another one:

 

Last Thursday, I visited the Langhian Weißenegg-formation about 30 km south of Graz. I have only checked out areas north of Heimschuh in the Sausal hills this day, that I have prospected already four years ago for coral specimens. The Weißenegg-formation is mostly limestone, containing in some parts coral carpets and patch reefs, witness of the subtropical to tropical climate in this area about 15 Million years ago.

Fossils in the "wild" (aka forests) are not super-abundant in this formation, with corals being the most common, but there is a very large, active quarry for portland cement fabrication in Retznei nearby, that is famous for all kind of marine stuff, incl. Meg teeth and other large vertebrates. But as some of you may know, I am not interested in active quarries ;). (Note: The quarry operators are very cooperative and supportive saving fossils encountered during mining, and fossil collectors are welcome!)

 

Quite a distance below a small limestone cliff in a forest north of Heimschuh, this coral specimen was presenting itself on the soil below an overturned tree. Its shape is essentially that of a half-cone (pic middle left, above red object, specimen as found, untouched). It is a chunk of a coral colony that is very nicely weathered all around, with absolutely no ding. Scelletal elements are more strongly weathered than the infilling sediment, so the specimen is essentially a negative. I have tried the usual method inverting the greyscale pic, see lower left. Preservation is very good, I think it is a Montastraea sp., considering the size of the corallites, strong costae and spongy columella. Such nicely weathered specimens are very rare, its only the second one that nice that I have found in this area.

 

Date of discovery: 10/17/2019

Name: Coral Montastraea sp.

Age and Formation: Langhian, Miocene / Weißenegg-formation, Styrian basin, Eastern Alps

Locality: Kittenberg, Heimschuh, Sausal, Styria, Austria

Ok, Ken, I'll throw in. :D 

 

Trilobites in the Amherstburg Fm are a distinct minority, and almost always present as disarticulated bits caught in the tangles of bryozoans and coral. Finding more complete than that is a real stroke of luck.

 

This one is not fully complete, but somewhat close (and much closer than the litany of bits that generally appear). Preparation on this one would not really improve its lot. The precise species is still uncertain, although there are some potential candidates as described in Lieberman's masterful efforts at revising the proetids of Eastern North America. For now, I'll keep it to genus. Pictured here is the positive and negative.

 

Date of Discovery: October 12, 2019

Scientific and/or Common Name: Pseudodechenella sp.

Geologic Age or Geologic Formation: Amherstburg Fm (Lower Devonian)

State, Province, or Region Found: London, Ontario, Canada (imported fill, possibly from nearby Ingersoll).

Great color on this tooth, do they usually preserve with this pattern?

I figured that I would put in this cool piece that I recently found in the upper level of the St. Leon road cut, I never found one like it before and from other pictures that I have seen, it seems to be pretty complete.

 

Date of Find:              10-12-19

Name:             Oncocerida Orthoconic Nautiloid 

Formation/Age:     Saluda Formation, Ordovician

I think so. The only depiction of the holotype is a sketch, and I can find no other examples of this species in literature.

(Geological Survey of Illinois Vol. 4. Figure 7a)

 

The related species Paracymatodus from the Pennsylvanian of Russia (Handbook of Paleoichthyology Vol. 3D) does have a very similar stippling pattern however.

Please remember to keep extra discussion of the fossils presented off of the FotM topic.  ;) 

Thank you.

A few of our fossil club members took a two day trip through NE Iowa and SW Wisconsin looking for trilobites. I found a few that could be entered for fossil of the month , but I rather liked this orthocone nautiloid found on the trip. My hunting partner was splitting rocks when he called me over to look at a cerarus cephalon he had found. As I stood there, I told Marv, look under your foot. There is a cephalopod there. Then I went back to my "hot spot". An hour later I went over to visit with Marv again and he still hadn't teased the nautiloid out of the rock and made it clear he wasn't going to. He is strictly a trilo person. So I retrieved my rock hammer and had at it. After exposing 4 inches of it, the body disappeared and I was left with just the siphuncle on further uncovering. To my surprise, way back in the rock, the body returned!!!! When I returned home, I just kept looking at this unique fossil and thought, why not enter it in this month's competition. It is freakish but enticing.

 

Date of Find: Found 10/23/2019

Name:  27 inch Orthocone Nautiloid with Exposed Siphuncle, likely Endoceras    

Formation/Age:  Platteville Formation, Ordovician

Location: Grant County, Wisconsin

@minnbuckeye cool find! I've been looking at your photo for more minutes than I would like to say... so just to be clear, you took 2 photos (on garden tiles) and put them onto a picture with leaves, right? Because the 'continuity' of the leaves is really confusing. Sorry for the very random question btw :wacko:

I like trilos as much as the next guy, but I don't know why anyone would limit themselves like that. I guess in such a vast and diverse field you choose to specialize, but why not collect it if it's there begging you to?

@Wrangellian, His loss was my gain!! But I must admit the trilobites we were finding were nicer than the cephalopod. I just grew attached to this one!!!

 

 @Max-fossils, I attempted to send a response yesterday and forgot to hit send. So here is a second attempt to explain the picture. The center ceph in the leaves was the background photo. To it, I added the other ceph pictures above and below it. Here are the individual pictures:

I am trying to hurriedly mount this beast to a board for support. Hopefully I can get a better picture submitted before the polls close.
