The Paleontological/Present Day Chondricthyan diversity of the Mississippi River
Joseph Fossil posted a topic in Questions & Answers
The Mississippi River has (in one form or another since the shrinking of the Western Interior Seaway) been flowing for 70 Million Years. https://www.smithsonianmag.com/science-nature/geological-history-mississippi-river-180975509/ This may be more of a current biological rather than paleontological question, but I'm curious about the origin of the current chondricthyan diversity in the Mississippi River? Now a fair amount of you might be confused when I say "Chondricthyan diversity in the Mississippi River", but this is truly a cool case of truth stranger than fiction. -
Found this a while back and had it in my unidentified pile. I assumed it was a small mammal rib and probably un-identifiable, but I took a second look recently, and there's something about the shape that doesn't quite look mammal to me. It also seems older than many of my finds because the entire in-fill at the broken end appears fully mineralized. I figured it was worth asking about. @Harry Pristis @Shellseeker @JohnJ @Meganeura @GPayton @garyc

Not sure if I've found a fossil. Can anybody help me ID this, please?
Flashgordon posted a topic in Fossil ID
Hi everyone, my sister and I went out on walk at a local nature reserve this morning in the UK. With the weather being so hot recently, water levels have dropped in the ponds and the lake that are situated in the reserve. I found this shell sitting at the edge of a very hidden pond. It was NOT found in rock, it's very light weight, very fragile. Is it still a kind of fossil? Thanks guys -
Don't ignore the 'gators, but here's something else to be cautious about: "BEACH IN FLORIDA CLOSED AFTER BRAIN-EATING AMOEBA CONFIRMED IN TEEN" This is Port Charlotte Beach, fresh water at the mouth of the Peace River. The amoeba thrives in warm temperatures (up to 115 degrees Fahrenheit) and enters the body through the nose when a person’s face is submerged in the water. The amoeba, Naegleria fowleri, normally eats other organisms like bacteria, but it can attack brain tissue if it’s not treated in time.

Upper Carboniferous (Duckmantian) Fish/shark tooth from coal measures. N. Wales.
Skatetom posted a topic in Fossil ID
Hi people! I'm a PhD student studying a Duckmantian fossil forest in North Wales. I have found these phosphatic fish/shark? teeth and scales I need an ID on. I suspect they are Adamantina Foliacea (Cuny and Stemmerik 2018) but that is a marine shark and this sequence is almost certainly completely freshwater and thought to be an upland swamp. I'm currently doing isotope work on the nodules and plant fossils and that appears to be confirming this is a completely freshwater system. Anyone have any ideas? You'll have to click on the images again once you've opened them to- 6 replies

Triassic Bivalve Imprint from the Triassic Basin NC (~230 Ma)
AlexSciChannel posted a topic in Member Collections
Here is a picture of a Bivalve imprint I found whilst in a Creek in Western Wake County. I was in the Triassic Basin and they have fossils dating back around 230 Ma ± 2 ma. It was part of the Carnian Stage of the Triassic part of the bigger Newark Supergroup. I presume it is a freshwater genus but I don't hear much about freshwater Bivalves when it comes to Triassic fossils. -

Hi everyone, I just got to spend a couple days looking for fossils at Lake Michigan and came across a few that I couldn't identify. In addition to loads of Petroskey stones and Charlevoix stones, I came across the attached rock. Any thoughts on what may have been captured here? The stone is about 4 inches across at the longest (top to bottom in the figure). Location: Charlevoix, Michigan.

Any ideas on what bone this might be? I have found several whale vertebra in the same location.
bitterlily posted a topic in Fossil ID
I found this bone today in a freshwater creek in Virginia, along with some old scallop shells. I’ll post a four pics of this bone first and then the others that I found last week that were pretty certainly identified as a small whale vertebrae and a flipper phalanx. Curious what this new one might be. Thank you! -
Is there any way to identify this jaw found in a freshwater creek in Virginia?

any way to know if these two bones might come from a similar animal?
bitterlily posted a topic in Fossil ID
Would it be possible that these two bones would come from a similar animal? I have been told with pretty good authority the larger is a whale vertebra and am curious about the smaller, found in the same creek, 100 feet away. Also Chesapecten shells found in the same creek. -

Way to identify the name of this type of shell found in Virginia, Freshwater, with fossils
bitterlily posted a topic in Fossil ID
These shells all look similar in nature except the last one, pictured by itself. Any way to identify, specifically? Thank You! Freshwater Creek, very slick light brown clay bottom which is blue grey once penetrated and dug. Also sand. -

Photo: top left Found in a small (10ft wide) woodland stream near the LA/MS border, (East Feliciana Parish, LA/Wilkinson County, MS) within the Citronelle Formation; formed during the Pliostene. While the Citronelle is oft noted to contain fewer saltwater fossils than expected for an ancient coastal plain, this stream has provided probably 95% of the marine fossils in my collection. As a longtime rockhounder but fresh off the boat newbie to fossil identification, I've struggled to find a match for this fossil. (The photo is one I had on hand, am preparing to paint and
