Dug into this park on Tuesday for a few hours. I really have no experience with Mesozoic strata, aside from Coon Creek of Tennesse. The water was inconsistent in it's depth due to a local beaver dam causing higher than normal water levels. Material here consists of unconsolidated clays, gravel and sand. Here are two large bivalves I recovered from the upper beds containing clams. I believe these are Exogyra costata which are common at this location. This tooth belongs to Scapanorhynchus texanus in which the teeth are referred to a

Recently got back from a trip on Holden Beach, and just WOW. Words can't describe the uniqueness of being able to find Mosasaur teeth next to Megalodon teeth. The recent Hurricane brought in many new fossils and I had quite good luck. Here are some photos of the trip, I will post a picture showing all of my best finds shortly, but for now enjoy! First, here are some of the Squalicorax pristodontus teeth I collected. These were relatively common.

Near-perfect meg tooth from Greens Mill Run North Carolina, and other goodies
fossil_lover_2277 posted a topic in Fossil Hunting Trips
Went fossil hunting for the first time since Holden Beach in May this past Tuesday at Greens Mill Run in North Carolina. Found my best meg EVER!! A near perfect 3 and 15/16 incher (just missing a tad bit of enamel beneath the bourlette on the front). Most megs at GMR are already fragmented and/or worn down in-situ, so extra happy about this one! Also found a Ischyrhiza mira sawfish rostral tooth tip, a huge exogyra, and I believe a nice Chesapectens masidonius? Also a baleen whale ear bone fragment, and a brown item I think might be a worn cetacean ear bone? Also a piece of petrified wood, a g -

I have a real mystery fossil I found in 2004 from Lumpkin, Georgia. The formaton is the Upper Cretaceous Ripley FM. US 27 was being 4 laned and quite a bit of new material was exposed in the road cuts. I think I was within a quarter mile of either side of the well known Frog Bottom Creek Upper Cretaceous fossil site. I found Exogyra costata, Flemingostrea subspatulata, Pycnodonte mutabilis, casts and molds of gastropods and pelecypods,worm burrows, etc. The oysters have well preserved shells, and the rest of the shells are mainly impressions and casts. Originally I just glanced at the mystery

Last January 12, I found some Exogyra sp. oysters in a limestone Late Campanian / Early Maastrichtian strata (SE Pyrenees, Catalonia, Spain), who turned to show abundant beekite rings. I owe to @abyssunder my knowledge of this mineral phenomenon, which, in my area,occurs mainly over laminar-type shells like oysters' (It can occur on other fossils, though). Have you fossils with beekite rings ?

Fossil exogyra oyster shells for trade
FossilizedJello posted a topic in Member Fossil Trades Bulletin Board
Hi, I live very close to big brook, NJ and have collecting many beautiful specimens of the oysters there. The oysters there are very unique, as they are some of the best and biggest of the species you can find in the world. I have many various specimens. Ill take any request for size, look, style as they all look different. Perhaps some like a more wavy pattern or separated pattern or a bubbly pattern. Im interested in anything you have to offer! I attached various pics to see. Although I have many and some even better. -

Nice Gryphaea and exogyra oysters..very large ..biggest is 5.5 inches -
Took a trip to eastern part of North Sulfur River near Cooper this afternoon. Water levels pretty low. About foot deep in most places. After walking down the bridge, I immediately noticed huge amounts of Exogyra oysters exposed everywhere. I usually find smaller ones in the past, but this time there were some huge ones that measures 6 inches across and weights 5 pounds lying on the surface. I only grabbed the ones that were less worn for my collection. There are still large amount everywhere.

I have an Exogyra costata from the Peedee Form.(Maastrichtian) in North Carolina that has an oddity embedded in the right valve. It is not a shell or barnacle attached to the surface, and is almost perfectly round ,unlike any boring clams I have seen. I have picked ( dental probe) around the oddity to confirm it has depth and is not a surface attachment. It appears it was hollow as it is now filled with hard sediment. It has been suggested this may be an example of bioimmuration of some sort. Anyone have any ideas ? Thanks.

In the daylight, this is an articulated Exogyra shell from the Cretaceous New Egypt Formation as it runs through Mullica Hill, New Jersey. I brought it home because it had an interesting bit of vivianite replacement covering half the surface of one valve. When I brought it home, I noticed some white material inside the cavity of the broken shell. I figured it might be calcite, which sometimes fluoresces. So, I pulled out my UV lamp. To my shock, not only did the white material glow an interesting powder blue color, but the majority of the one valve glows an intense, bright red! Meanwhile, the -
Hi, Recently I found this quite complete (both valves) oyster shell in an Upper Campanian to Lower Maastrichtian strata in SE of Pyrenees. My guess is Amphidonte pyrenaicum, a widespread species in the Tethys at this epoch. Supposing my guess is correct, problem is that I find that species named as (from older to newer papers): Exogyra pyrenaica, Ceratostreon pyrenaicum, Amphidonte pyrenaicum, Amphidonte (Amphidonte) pyrenaicum, and Amphidonte (Amphidonte) pyrenaica. So, I understand that former Exogyra genus has been splitted, Anyone knows of a

I'm studying fossils and I'm having a difficult time understanding the visual(and structural) differences between Exogyra and Gryphaea. Any insights would be very much appreciated!

In early July 2016, I encountered a virtual self-guide field trip posted online by Pete R. Rose, PhD in February 2012. He describes an Eagle Ford (Kef) outcrop exposed in the parking lot of Barton Creek Mall in Austin, Texas. I went there to check it out. The USGS webviewer only designates the area as Georgetown-Del Rio. But, the U.T. Bureau of Economic Geology has an accurate Geologic Quadrangle Map #38 that shows this feature. But, it predates Barton Creek Mall which is not on the map. Interestingly, the Austin Chalk Atco Member caps the nearby hilltops, but it is heavily weathered to
