Miocene_Mason Posted June 26, 2018 Posted June 26, 2018 Best (and one of the only) vertebrate bone I’ve found this month. Need to get out more! June 23, 2018 Crocodilian Vertebra Paleocene, Aquia Formation Purse State Park, Charles County, Maryland 3 Happy hunting, Mason
Paciphacops Posted June 26, 2018 Posted June 26, 2018 For consideration of F.O.T.M. is a piece of an orthocone cephalopod , with a siphuncle filled with graptolites in matrix. On the same rock is a piece of another cephalopod, or part of the same, that has been replaced with calcite crystals, except the siphuncle, which is also filled with graptolites in matrix. Date of discovery: June 14, 2018 Name: Graptolite Amplexograptus perexcavatus Age: Ordovician Lebanon Limestone Location: Marshall County, Tennessee "Don't force it, just use a bigger hammer"
deutscheben Posted June 28, 2018 Posted June 28, 2018 My entry this month is the first non-plant fossil I have found from this particular spoil pile. Unfortunately, I could only find one half of the nodule. Date found: 6/23/18 Name: Palaeoxyris prendeli shark egg capsule Age: Pennsylvanian, Carbondale Formation Location: Vermilion County, Illinois 2

Kane Posted June 30, 2018 Posted June 30, 2018 And one for VFOTM while I'm here.

caldigger Posted June 30, 2018 Posted June 30, 2018 Kane I'm sorry, but according to the FOTM supplemental rules (that I just made up), moderators are not allowed to enter the contest. You will now have to withdraw your entries. Something about an unfair advantage of being in charge of the ballot box.

I am wondering if we can adjust the info required for submissions: like Scientific Name: followed by something non - scientific humans can understand...extinct armoured, jawed fishes and then something that provides the age like 419 million years ago (mya) to about 359 mya I see this in multiple submissions where my first action is to search the internet or Wikipedia. Thanks Jack Should have added: Love the skin.... The White Queen ".... in her youth she could believe "six impossible things before breakfast"

Shellseeker Posted June 30, 2018 Posted June 30, 2018 7 minutes ago, WhodamanHD said: At least your learning, especially from such a reputable source Agree, I do not think the answer is clear_cut. I am asking the Admins/Moderators to consider the pros and cons. When looking at FOTM entries or in fact numerous submissions in Fossil ID, I will usually go to the internet because I want to know what geological age in MYAs, I'd like a picture or artists rendition of the fossil, what exactly is it beyond the Scientific name.. While TFF members no doubt have significant scientific knowledge above the average American education , I think few can determine all that from the fossil photo and location. We have new TFF members (thankfully) all the time and sometimes we are asking them to drink from a fire hose. We all learn from seeking answers we do not understand.. That is the big positive... That is why I see this as a balance, and leave the heavy thinking to Moderators... The White Queen ".... in her youth she could believe "six impossible things before breakfast"

We just pulled some placoderms out a week and a half ago along with a ton of jawless fishes. Good placoderm material is always really rewarding to find. How certain are you that's Protitanichthys though? It looks slightly more like it might belong to something a little more primitive, given the coarse and highly-regular tuberculate pattern. Just a thought.

It looks slightly more like it might belong to something a little more primitive, given the coarse and highly-regular tuberculate pattern. Just a thought. Not absolutely certain at all (hence my preceding question mark on the name, and the "tentatively" qualifier), but the closest match to the formation thus far. There hasn't been much study on placoderms in the Widder Fm, as far as I know, but I hold out hope to bump into a placoderm expert here on TFF. The tuberculate pattern on P. rockportensis does vary, pending on where the piece is located on the head shield. At times they appear asteroid in their arrangement, and at other times more uniformly distributed to the point of disappearing at the edges of the cephalic shield. Also, age is a factor in how these tubercles manifested. The closest I've come to any study that can be roughly analog to this area would be: Case, E.C.
