My first fossil and I'm already stumped - hoping someone can point me in the right direction here! My husband is a geologist and brought a piece of shale home with a fossil poking out. I've been chipping away inexpertly, and can't figure out what I'm looking at. This was found outside Birmingham Alabama, in the Mary Lee Formation, near the Pratt Seam. My husband tells me the area was freshwater swamp during the Pennsylvanian Period. What am I looking at here? I know it shouldn't be soft tissue, but it doesn't seem to be plant, shell, or bone, either! Please set me straight! I hope these pictures are ok - as you can see, I'm not done cleaning it... but I'm trying to be cautious since I'm learning as I go. Also possibly relevant: the shale was riddled with dark colored fossil plants. My husband said they were carbon - they nearly disintegrate on contact. I've included a picture of those, too. Here are pictures of the plant fossils in the rock that were exposed when we broke it apart. The mystery fossil is on the top of the left rock. Thank you all!

Veggie-exchange: Plant fossils from Piesberg quarry (Germany)
paleoflor posted a topic in Member-to-Member Fossil Trades
L.S., To liberate storage space, I would like to offer the following plant fossils for trade. All specimens below come from the Late Carboniferous of the Piesberg quarry near Osnabrück (Germany). Scale on photographs in centimetres (1 inch = 2.54 cm). Specimens B, C, F and G show neuropterid fronds of various sizes (most likely Laveineopteris rarinervis). Note specimens B and G were recovered broken and have been glued/repaired. Specimen E is a large plate and shows reproductive structures of Calamites (E-1), a Laveineopteris frond (E-2), a strap-like Cordaites leaf, and some Annularia-like leaf whorls. If interested, I could also offer the counterpart of E. If preferable, I can cut specimen F to size (currently large slab of rock for the actual imprint). In general, please note that these specimens are rather large and heavy (I will cover the shipping costs, but you will need space to display these pieces). In return, I would be mainly interested in plant fossils from the Devonian to Cretaceous (but feel free to offer younger material also). Kind regards, Tim Specimen B: Specimen C: Specimen E: Specimen F: Specimen G:

Hi fossil friends - I've been away from the board for a couple of years, settling into retirement, now getting back to some fossil fun. I'm sorting through my St. Clair inventory which is now pretty large since that was where my wife and I did most of our collecting when the site was still open. So now I have quite a few plant fossils and am organizing and prepping them - not sure what I'll do with them. These two items are the last fossils we collected from St. Clair before they closed the site - the large one is 25 inches long and was cut by someone (probably the idiots who ruined the site access). Most pieces are smaller and individual specimens. I'm organizing, labeling and putting in Riker mounts now. Interested in any suggestions how to proceed? I also have a collection of unique mangal shoots we collected at a secret site in central New York which are unique and probably somewhat rare.

From the album: Carboniferous Plant Fossils in My Collection
This is another view of the same Trigonocarpus, this view showing the open end of the seed. Seeds of seed ferns - this was probably from Medullosa - had open ends to allow pollen to enter. It is thought they were fertilized by pollen when they dropped into the water although a few paleobiologists believe insects may have pollinated them through the opening. Also why were the seeds encased in a fruit like covering (like avocados)? To be consumed by creatures that lived in the shallow swamp water? -

This is another large Trigonocarpus from St. Clair, which is contained intact in the shale substrate. The entire seed is visible. -
Trigonocarpus - Carboniferous Seed from St. Clair (1a)
hitekmastr posted a gallery image in Member Collections
From the album: Carboniferous Plant Fossils in My Collection
This 2 inch Trigonocarpus is a seed of a Medullosa (pteridosperms seed plants) which grew in shallow swamps abour 306-308 million years ago when St. Clair, PA was located near the Equator. Leaves associated with this seed & tree include Alethopteris and Neuropteris. It is thought that these seeds were encased in fleshy "fruit" like an avocado. The seeds were open at the pointed end to allow pollen to enter when the seeds dropped into the water in the shallow swamps where these trees grew. These were the largest Carboniferous seeds, growing up to 4 inches. -
Hi guys! Long story short, a rather large collection of Mazon Creek fossils has been donated to my university. I thought I'd share some pictures of the collection and confirm some preliminary identifications. There are a lot of specimens so I will probably split this into two posts. Annularia radiata Annularia stellata A whole bunch of Annularia stellata?

Goniodonts - strange echinozoan teeth from the Carboniferous
TqB posted a topic in Member Collections
I was surprised to see this specimen for auction and pleased to win it. It's Anguloserra thomasi, a rare tooth from an ophiocistioid echinoderm and comes from the same locality as the holotype described here (abstract only): Haude & Langenstrassen 1976. I've been interested in these since finding three similar specimens in the UK that took a while to identify - shown in the next post. It's preserved as an impression - most material in this matrix is decalcified. Carboniferous, upper Mississippian, Culm beds (equivalent of Brigantian and Arnsbergian beds in UK), Aprath, Germany. Scale in mm. Here's the holotype from the linked paper (a latex cast):

In a previous post i showed some finds from the British Coal Measures of Derbyshire , this is a small nodule from there it measures 21mm long x 12mm wide and the longest pinnule is just 4mm . I have tried to show it's size in these 4 pictures. and just so you don't get bored looking at the same fossil here is a.... Asterophyllites Equisetiformis Cheers John

A friend of mine recently brought some property southwest of Brownwood, Texas. The land is largely Pennsylvanian. The formation is Garner, which he says the description says it is marine with megafauna. He sent me these pics (below) this morning. He found this last week. He said it was just laying on the ground and didn’t see the source of it nearby. At first I thought it looked like some weird type of wood I had never seen before, but now I’m wondering if it could be geological. I have requested an end view, side and back side pics of it. He won’t be able to get them till this evening though. I think it’s pretty cool looking whatever it is. I appreciate your thoughts and comments on it.

Was up at Lake St. Clair, NSW looking for late(?) Carboniferous marine fossils and came across this thing. I am thinking that its a fish tooth but not too sure as no vertebrate material has been reported from the site to my knowledge. Please let me know if clearer photos are needed This specimen is aprox. 7 mm long Thanks,
