I've recently started having an interest in Paleozoic fossils simply because I've never actually found any. I live in southern California and recently went near the area of Corona to check out some of the paleozoic rocks. Unfortunately all seemed to be highly meta-morphed with hardly any trace of fossils, if any. So my question is, how do I go about finding paleozoic material in southern California? Are the metamorphed rocks hopeless? Thanks in advance

Kathleen B. Pigg of the University of Arizona notes that this "stem subsurface pattern that is sometimes called 'rabbit tracks'. The double track you see is probably a result of a pair of air channels that accompany the leaf trace through the cortex. The vertical ribs are produced by an increase of bark through secondary tissue production." The pair of sepicemns in the first image are the positive and negative impressions of the same piece. The second image is a detail from the same specimen.

How did some early Paleozoic animals expand to distant continents so fast?
Hapchazzard posted a topic in Questions & Answers
I've noticed that a lot of clades that first appear in the early Paleozoic seem to immediately be present across the globe, even though the continents at the time were mostly disconnected and separated by oceans. For example, (calcified) trilobites suddenly appear in Cambrian Stage 3, but are already present in Laurentia, Siberia and parts of Gondwana, despite the vast distance and oceanic separation of the landmasses. Similarly, Rugose corals appear in the late Middle Ordovician, but already seem to present across the equatorial regions of the globe. How did these benthic/sessile clades(so I'm not referring to pelagic trilobites) manage to spread geographically wide so fast? Is there any way we could know what landmass was the actual "birthplace" of some of them? -
Hi, I was just wondering what was considered large for a single Edestus heinrichi tooth. I have recently bought one and it was around 1.6" wide. It was labeled as being big, but I just wanted another more experienced opinion on it. Thanks for your time.

My kids found some fossils near Roanoke, VA - It looks like they are brachiopods and trace fossils from outcrops ranging from the Ordovician to the Mississippian. Can these be more specifically identified besides generic "brachiopods"? Thanks!

On the winter solstice, we took the family out for a 7-mile winter hike. Luckily it was winter in name only, as the temps got up to almost 50 degrees. We found a nice trail near Roanoke, Virginia, that took us into the Appalachians. As the kids are still excited about our giant fossil hunting trip out west this summer, I decided to pick a location where I knew there were fossils to be found. All I know is that these were Paleozoic formations, where 450mya it was swampy mud flats. So I could tell them we wouldn't be finding dinosaurs, but we might find some shells. So they enjoyed the hike, and spent tons of time looking around for fossils when our climbing reached the tops of the ridgeline. Then we had to tell them they'd be carrying these rocks with them for the next 6 miles.... 1st kid's finds: (large flat-ish shells) (these seemed to be the most common finds) (trace fossils?) (crinoid stems? - Near the 1" mark, top/bottom)
