Entries - November 2010 Finds Of The Month

[JohnJ]

Thanks Shamus. Plant material from this area is not common... this could be one of my best finds this year....

Peter

Yet another of your interesting micro finds! I hope you can get a definitive ID to make sure it qualifies as a valid entry.

Yes ... I am getting image sent off to the ROM this morning ... hoping to get an ID before the deadline.... as suggested by Steve... this could be seaweed sun dried like raisins... I will let the experts determine this.... one way or the other I will let everyone know the results... having lots of fun.

Hi John:

Entry #2 is withdrawn..... ID is modern plant by the ROM... " I'm not at all sure that this is a fossil ... it doesn't look integral to the limestone matrix. My guess from the images is that it's a carbonized fragment of modern plant or algal material. If you can slip the tip of a fine dissecting needle under the distal portion (right hand end in image 02496) and peel it free from the rock surface, you will have your answer.".... OH well.... It was exciting for a little while with hopes and anticipation... at least I have a photo... and now when I get home will immerse the fossil in an ultrasonic bath and see if it floats off....

I think I will crawl back under a rock now for the rest of the day.....

Here is my vertebrate entry : Fossils from the Michigan Basin:

Object is a fish tooth of some kind.... possibly from Osteolepiform fishes or Sarcopterygian fish tooth (PzF)

Middle Devonian

Hamilton Group

Found Oct 30-31/2010

Found in Clay Pit at Hungry Hollow ON

Prep Nov 1/2010 with Ultrasonic bath unit

Dimensions approx 2mm in length these are tiny

Tooth ID confirmed Nov 23/ 2010 by ROM bone expert KS

"It certainly does look like a "fish" tooth. I'm not familiar enough with Paleozoic fishes to say for sure what KIND of fish it is. I looked at our rather poorly preserved samples of Devonian Onychodus, and from what I can see, there don't seem to be any striations on the teeth. Apparently some of the Osteolepiform fishes do have striations, from the illustrations I've seen in books. So maybe an osteolepiform fish of some sort? That would be my best guess at this point. It is tiny, so there may be other possibilities, like an early palaeonisciform fish?"

It's No problem Shamus.... this was a learning excercise (that is why we are here ) and I am glad we got the ID correct.

With the labyrinthodont texture of the tooth, it is likely a Sarcopterygian fish tooth, although the teeth are generally not diagnostic. Fun tooth though. Now if you found a tooth whorl, that is a bit more diagnostic (anterior tooth of a Onychodont).

cheers,

Thanks for your insights PzF... Sarcopterygian fish tooth.

thats amazing peter..........a devonian fish with killer teeth

how did you ever find him!?

anyway....great find!

lol Thanx Right now I would trade you for about 5 to 6 months lol

I agree 5 or 6 months without fossil hunting, I don't know how i'll survive. :coldb:

A big thank you to our forum member Placoderms who first found what looked like teeth from Arkona in the spring of this year ... followed by emails and thus Placoderms find inspired me began the quest for teeth and fish remains at Arkona... I found Placoderms saw mark cuts in the rock this summer and looked for rock of similar type at each of my visits to Arkona.... the rock looks granualar almost like a coarse sandstone filled with fossilized debris... looked like coarse sand paper from a distance..... the tooth resting on a mud caked limestone plate partially reflected sunlight making detection possible.... although this tooth was found at the bottom of a clay pit.... its origin is probably from upper rock layers

i have to go throught that every year...

[bear-dog]

Love the echinoids.I have never found a group of them in matrix here.I did however see a grouping of 30 or more a poor guy worked on for several weekends.He got it down to less than 30 minutes to remove it and planned to come back the next weekend.30 min.later a guy came by and seen it.

I explained to him the guy worked every weekend to remove it ,to please leave it alone.He told me it was his now.I took some pics of his boat as well as him removing the echs just in case.The following weekend the poor guy pulled up and nearly cried then began to stare me down[without accusing me].I told him I knew what he was thinking and I dont roll like that.[i play by the golden rule,treat others the way you want to be treated].

I then showed the pics to him.

I later found out he works with the guy and told him about hunting there.

This is my Vertebrate entry for November.

Mid-Eocene

Tallahatta Formation- Alabama

Species- Ginglymostoma (Nurse Shark)

Discovered - November 25, 2010

After a heavy Thanksgiving meal and the thought of endless re-runs on TV, decided it was time to sift through the tailings from my last river trip. We wash matrix through 1/4 inch screen and trap the smaller sand in window screen then place this in a bucket to go through later after it dries. Thanksgiving was that later date, after going through handful after handful of sand on a paper plate, found some interesting tiny's but one of interest. Nurse shark teeth are not abundant but considered one of the more difficuly teeth to find in this formation with specimens averaging in the 6mm range. This little guy is a gigantic 3mm and almost went un-noticed in the sand matrix.. This tooth is far from being a Meg but some of these tiny's have an interest all their own, it's a small world out there too.

foshunter, very nice specimen

congrats

Hi Steve,

Do you mean this shark had laid in some fresh water?

I just received the eggcase. Thanks a lot, it is very interesting ! Is it from a Palaeoxyris ?

I have found this link on the web :

And this one, but it is only the 1rst page http://www.schweizerbart.de/resources/downloads/paper_previews/74838.pdf

Hi Coco.... I'm glad it has arrived in one piece..... Yes its a Palaeoxyris, Upper Carboniferous, Duckmantian.... so now you have a fossil shark eggcase for your collection to show people to compare when you show them your modern ones...with your love of fossils I thought you would like it.....

''Do you mean this shark had laid in some fresh water?''

I was informed by a very knowledgeable palaeontologist who specialised in my local carboniferous fossils that the white clay (kaolinite) infill is often a good indicator that these nodules formed in a predominantly freshwater to brackish, rather than brackish to marine setting...so in this instance we can only presume you are correct as there is a good layer on the eggcase...

Love it...I don't have any of these yet but I think they are very cool!

Fully inflated 3D Devonian Phacops Trilobite in enrolled position, found Oct 30,2010; prep Nov 1,2010 with Ultrasonic Bath. Location in the Clay Pit at Hungry Hollow ON near Arkona... Hamilton Group.... Size is about 1/4". Note the finely detailed compound eyes. A bit weathered but still intact.

Amazing!!!!!
