Gandoril Posted August 18, 2019 Share Posted August 18, 2019 This is the first time I've tried to go looking for fossils and found this while breaking apart some sedimentary rocks. I don't know if I'm seeing the cross section of something. The lighter grey, white area really stood out against the normal red yellow white of the surrounding stone. Located near the edge of a creek bed. According to the usgs the area is Felsic Metavolcanic Rock and in the period of Cambrian/Late Proterozoic.

Rockwood Posted August 18, 2019 Share Posted August 18, 2019 I think usgs torpedoed you out of a chance on this one. The odds of finding an identifiable fossil there are close to zero. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted August 18, 2019 Share Posted August 18, 2019 Do not take a granite for a fossil. Agee: not a fossil. My goal is to leave no stone or fossil unturned.

Fossildude19 Posted August 18, 2019 Share Posted August 18, 2019 Welcome to the Forum. Looks like metamorphic or igneous rock, to me. Sorry, not seeing any fossils.

Rockwood Posted August 18, 2019 Share Posted August 18, 2019 1 hour ago, Gandoril said: Metavolcanic Rock Perhaps you were confusing this with a truly sedimentary rock composed of volcanic ash ? Such rocks do contain fossils, and they look very igneous until you identify an obvious fossil in it. Link to comment Share on other sites More sharing options...
Gandoril Posted August 18, 2019 Author Share Posted August 18, 2019 Bummer, thought i might have gotten lucky. I just assumed it was sedimentary based on how flaky the rock was and that its surrounded by clay. Did find a ridiculous amount of iron in it. The search continues Link to comment Share on other sites More sharing options...
caldigger Posted August 18, 2019 Share Posted August 18, 2019 If you haven't already, take a look see in the Forum topic "Fossil Locations", scroll down to North Carolina. You might find a locality near you with a track record of having fossil material. Link to comment Share on other sites More sharing options...
grandpa Posted August 18, 2019 Share Posted August 18, 2019 Welcome to the fossil forum. NC has a large # of places to find fossils. If you have the interest, I'd recommend joining the NC Fossil Club, a really great organization with lots of great, helpful folks. Also, if still avail, there is a NC govnt published (1987) book on NC Fossil Sites. I picked one up at the govnt office in Raleigh in the early 1990's and found it quite useful. Some of the info may be outdated now, but much isn't. Link to comment Share on other sites More sharing options...
hemipristis Posted August 19, 2019 Share Posted August 19, 2019 The only sedimentary rocks that I'm aware of in the Durham area are the Triassic reddish mudstones associated with the failed rift called the "Durham Basin". They're exposed in at least one quarry there, and several railroad cuts. My paleo prof recovered an entire new species of reptile from the quarry. They nicknamed it "Alison" after his wife at the time. UNC research link You're better off driving eastward until you hit at least Goldsboro. That's when searching the riverbeds gets fun... Goldsboro has lignite & amber. As you proceed eastward, the more fossiliferous formations appear. The same professor wrote the book that @grandpa references, which is available from the NC Geological Survey: NC Geological Survey fossil book 'Those who cannot remember the past are condemned to repeat it.'

Plax Posted August 19, 2019 Share Posted August 19, 2019 Like Hemipristis said there are fossils in Durham. The North Carolina Museum of Natural sciences in Raleigh has some nice fossils from the Durham area and if my memory serves me they are also in conglomerates. If I lived in the area I'd look at rip rap along streams and bridges for Triassic fossils that were locally quarried. There are also no doubt natural exposures in the area. This is very difficult collecting with a good amount of research required. Most collectors just go where someone tells them to go and the book "Fossil collecting in North Carolina" has a lot of great sites. Link to comment Share on other sites More sharing options...
