Texas Permian Hunt
TyrannosaurusRex posted a topic in Fossil Hunting TripsIn my continued studies of my local Permian areas, I came across information on a site that I hadn’t been previously aware of. I’m working on a paper describing the outcrops in the areas near to Taylor, Baylor and Archer counties, as well as some close outliers when I come across them. Information on this site Clear Fork (Permian) 298.9-251.902 mya Lots of siltstone at this specific site, which is why there are tracks present. All the fossils came from an area about 10 x 15 ft in an outcrop that has weathered away, there’s lots of siltstone surrounding but the fossils were
Carboniferous Plant Hunt!
Petalodus12 posted a topic in Fossil Hunting TripsWith the semester having ended yesterday, I figured I would go hunting today at one of my favorite Carboniferous plant localities. It is located in Southwestern PA, and is in the Connellsville Sandstone member of the Casselman Formation, which is in turn part of the Conemaugh Group. It is late Stephanian in age. The Connellsville Sandstone itself represents a fluvial deposit made up of sediment from the then young Appalachian mountains. It is a very thick and massive layer; because of this it has been quarried for building stone for hundreds of years. The locality that I collect at is in a val
Pennsylvanian aged mystery-Gall or something else?
Petalodus12 posted a topic in Fossil IDHi all, Upon examining some of my finds from this hunt about a month ago, I realized that there was an anomaly on one of the Neuropteris ovata pinnules. Initially I brushed it off as nothing more than an anomaly, but last night while I was doing some reading I came upon an intriguing paper on insect galls from the Carboniferous. Some of the gall fossils included bore a striking resemblance to the gall on my frond, and so I figured I would make a post to see if any of you had an idea on what it could be. Here is the frond, in full view:
Late Pennsylvanian Seed Fern
Petalodus12 posted a topic in Fossil IDHi all, Here’s an interesting plant find. I discovered it in a locality in Western PA known for producing good plant fossils. I’m thinking seed fern, maybe related to Alethopteris somehow but to be honest I’m not sure what the species is. Any help would be appreciated. Thanks in advance Stratigraphy: Connelsville Sandstone of the Casselman Formation of the Conemaugh Group. Age-Late Pennsylvanian, ~305 MYA
Pennsylvanian Plant ID Help
Kpitch posted a topic in Fossil IDThese fossils were found in Westville, IL (Vermillion County) a long time ago by my great grandfather (the grey/black fossil; he worked in the coal mine), and my dad (the light brown/reddish one; on a slag heap). After reading this Publication Title: Guide to Pennsylvanian fossil plants of Illinois Publication Type: Geoscience Education Series Author: James R. Jennings Year: 1990 and looking at a number of photos for comparison, I am wondering if these are Alethopteris sertii? (other guesses are Neuropteris and Acitheca). At least that is my (un

Fossil Seed Ferns (Alethopteris Sp.) From St. Clair, Pa
z10silver posted a topic in General Fossil DiscussionFossil seed ferns (Alethopteris sp.). 300 m.y.o. St. Clair, PA. 185mm. One of the coolest fossil hunting experiences I’ve had. The amount of detail preserved in these fossils is incredible—some appear as if the leaves had just fallen! Exploring this area was like being transported back in time. Looking at a fossil like the one pictured here, it is not difficult to imagine the ancient carboniferous swamp coming back to life. For me, fossils are all about stress relief; a sobering—yet comforting—reminder of how briefly we are here, and where our priorities should lie. When I feel o
Arthropleura, A Pollinator Of Medullosa (Seed Ferns)
Stocksdale posted a topic in General Fossil DiscussionA bit of information I came across today in Paleobotany: The Biology and Evolution of Fossil Plants . Arthropleura may have been important for pollination of Medullosa (seed ferns such as Macroneuropteris and Allethopteris). It sounds like one of the lines of evidence is an arthropleura part from Mazon Creek. Interesting.....
Mazon Creek - Single Sided Nodule - Seed Fern Bark
evannorton posted a topic in Fossil IDHi Folks, Any thoughts on the attached...to me it looks a square of bark from a Medullosa noei (picture on Page 44 of The Mazon Creek Fossil Flora - Jack wittry). Any one have other thoughts - is this a square of seed fern bark?
