____________________________________________________________________________________


Rules for The Fossil Forum's Vertebrate and Invertebrate/Plant Find of the Month Contests

1. You find a great Vertebrate Fossil or Invertebrate/Plant Fossil! Only fossils found by you.

2. Post your entry in the Find of the Month topic. Use a separate post for each entry.

3. Your Fossil must have been found during the Month of the Contest, or the significant Preparation of your Fossil must have been completed during the Month of the Contest.

4. You must include the Date of your Discovery or the Date of Preparation Completion.

5. You must include the common or scientific name.

6. You must include the Geologic Age or Geologic Formation where the Fossil was found.

7. Play fair. No bought fossils.

Shortly after the end of the Month, separate Polls will be created for the Vertebrate and Invertebrate/Plant Find of the Month. The maximum entries allowed by the Polling software will be selected for each contest by the staff.

In addition to the fun of a contest, we also want to learn more about the fossils. So, only entries posted with a CLEAR photo and that meet the other guidelines will be placed into the Poll.

Within a few days, we will know the two winning Finds of the Month! Now, go
find your fossil, do your research, and make an entry!

Nice Jaw Darren!

Found this on my last collecting trip; out again tomorrow to see if I can bag any more nice specimens at a new chalk location. The ammonite here is around 15cm and the largest I have found in the chalk.

Acanthoceras rhotomagense

A. Rhotomagense zone, Zig Zag Chalk

I haven't been here "in person" for a while now, but I found something recently that I thought might be worth showing. Just finished preparing it this week.

Here is my entry for invertebrate find of the month. This was subject of a previous post. Fossils found on May 4 with preparation completed later on May 4.

Bryozoan

Archimedes Swallovanus (?)

Mississippian Age

Shale unit in contact with Bangor Limestone

North Alabama

These are by far the largest Archimedes I have ever collected, especially free of matrix with the largest previously around 3 1/2" long.

Here is my Vertabrate entery for the Month...

Ptychodus mortoni

Shell-crushing shark jawplate

Discovered: 5/4/13

Smoky Hill Chalk (L. Cretaceous)

Kansas, USA

post-6661-0-75080800-1368999437_thumb.jpg

Some info on Ptychodus-

~ A genus of durophagous shark (shell-crushing)

~Ptychodus has been found on every continent including Australia

~First discovered in England, thought to be "palates from fish"

~Had crusher teeth on both upper and Lower Jaws

~ Few specimens have included cartilage and even vertabrae remains

~Jaw plates like this are very rare

This is my first Invertebrate entry...

Uintacrinus socialis

Floating Crynoid colony

Discovered: 5/4/13

Smoky Hill Chalk (L. Cretaceous)

Kansas, USA

post-6661-0-09858900-1369013021_thumb.jpg

Little info about Uintacrinus...

~ The only echinoderm currently known from the smoky hill chalk

~ Related to starfish and sea urchins

~ Were apparently colonial and free-living (not attached to the sea bottom)

~ Named after the Uinta Mountains of Utah, where very fragmented remains were first discovered by Marsh in 1870. Better specimens were discovered in the Smoky Hill Chalk, few years later.

~ I was reaching for a big calcite crystal when I saw this specimen near a small bush.

Found next week and just prepared

:rofl::rofl:

Found last week ! It is the problem with foreigners, sometimes we have to think not to confuse two words (it often arrives at me, even with "last" / "next") !

Bon lundi férié à toi !

OMG! What a month!

Heck, if I would have to find a T-rex skull to compete with y'all!

But, unfortunately, due to my Kansas background, Im going to have a hard time not voting for the Unicrinus I've spent years trying to find a itty bitty piece of one, but have failed miserably. To see one here is fantastic! Plus it was found by one of my favorite members whose input and opinions I value highly.

Now for my vertebrate vote, I have no idea, even though I love ptychodus, and know how rare associated dentitions are!

Thanks, Boneman. That means a lot :)

I would like to add an amazing fossil to an amazing month. I never thought I would have a FOTM entry, but sometimes you just get lucky.

We went with the NYPS on their trip to the Lower Devonian of New York and I found this specimen laying on the ground on my way back to get the car to pick up the kids. The geologist for the mine ( who was amazingly helpful all trip long) said he had never seen one like it come out of there. The red color comes from the oxidising pyrite and is not crayon as some have suggested :P
