gobbler716 Posted January 8, 2018 Posted January 8, 2018 This is a very recent find from the Cahaba River Valley. One person on the Facebook page identified this as a belemnite. Is this the general consensus? To my knowledge I have never seen one. I have a regular paper clip for size reference.
izak_ Posted January 8, 2018 Posted January 8, 2018 How old is it? I don't think its a belemnite but some better pics may help.

JohnBrewer Posted January 8, 2018 Posted January 8, 2018 I don’t think it’s a belemnite but the pictures are too poor to really give any opinion. John Map of UK fossil sites
gobbler716 Posted January 8, 2018 Author Posted January 8, 2018 I will try to get one better. Most of the plant life I find is 300,000,000 y.o. plus or minus.

gobbler716 Posted January 9, 2018 Author Posted January 9, 2018 The area I hunt is a reclaimed coal mine, so the different layers by age have been commingled. In one trip you find calamites mixed in with clam-like fossils. Aging the area would be difficult. We find tons of calamites, then drive a few minutes and you find shark teeth. If you ask how old it is, I can't give a definitive answer. I hope this helps. 1
Miocene_Mason Posted January 9, 2018 Posted January 9, 2018 Sounds like the sea is retreating and coming back, not uncommon for the Carboniferous climate (the whole shark tooth thing I’m guessing is a different formation all together). The shininess of the fossil is bothering me, I can’t really make a judgement till I see sharper pictures. 1 Happy hunting, Mason

If you ask how old it is, I can't give a definitive answer. I hope this helps. There is however absolutely no question that all of these coal deposits are from the carboniferous, even if they are somewhat mixed up, so that rules out belemnite completely, since they first came into existence during a much younger age. I'd say either root or burrow. Greetings from the Lake of Constance. Roger http://www.steinkern.de/
westcoast Posted January 9, 2018 Posted January 9, 2018 Unfortunately those second set of pics aren't much better. What camera are you using? Can you try again? In carboniferous coal deposits it is common to find marine and non marine fossils very close together. But not belemnite.
gobbler716 Posted January 9, 2018 Author Posted January 9, 2018 West Coast, why is that? Too many years between species existence? Location?

westcoast Posted January 9, 2018 Posted January 9, 2018 10 minutes ago, gobbler716 said: West Coast, why is that? Too many years between species existence? Location? The coal formed along low lying coastal plains on delta margins. Slight fluctuations in relative sea level (due to delta sediment settling/compaction and/or global sea level changes associated with the carboniferous glaciations) meant these areas were inundated by sea water at fairly regular intervals. Some of the faunas are interpreted as living in brackish waters, so not fully open marine and not quite fully freshwater either. 2

Belemnitida (Belemnites) are an order rather than a species. They appeared during the Triassic period and existed up to the end of the Cretaceous. If you study a geological timescale you will see that the Carboniferous period is much older than the Triassic, which leads to the logical conclusion that belemnites did not exist at the time that the coal deposits which you are collecting were laid down. 2 Greetings from the Lake of Constance.

gobbler716 Posted January 9, 2018 Author Posted January 9, 2018 Thanks, West coast. That makes sense.
