Coral hunting in the Weißenegg-formation, Styria, Austria (Langhian/Badenian, Miocene) – 10/17/2019
FranzBernhard posted a topic in Fossil Hunting Trips
Hello! Finally, I have some time to post this fossil hunting trip from a warm and sunny day in October, 2019. Introduction The Miocene Styrian basin in Austria is mostly filled with various clastic sediments, e.g. fossil-rich “Florianer Schichten” around St. Josef. The “Mittelsteirische Schwelle”, a north-south trending high-zone of palaeozoic, slightly metamorphic rocks, however, is, in a very literal sense, the base of various biogenic carbonate rocks (“Leithakalk”). The individual carbonate bodies are of slightly different age – spanning the whole Badenian (about three Million years) - and composition. The younger ones to the north around Wildon are characterized by coralline algae and often oncoidic limestones, corals are extremely rare there. To the south, corals became locally an important part of the limestones, besides the coralline algae. No really big coral reef structures have developed, though; coral carpets and small coral batch reefs are characteristic. Various maps from the internet and literature of the visited area. 1 = Kittenberg; 2 = Hötzlweg Depositional scheme of the Weißenegg-formation around the “Mittelsteirische Schwelle”. Within the green rectangle the area of interest. Relief map of the area north of Heimschuh. Note the many very small to medium-sized quarries. Some cliffs are also visible. These corals are witness of tropical to subtropical temperatures in this area about 15 Million years ago. Coral development is considered to depend on local factors like sediment input or (non-)exposure to severe wave action during storms. Coral diversity is relatively high, with at least a dozen of genera described or mentioned. About four years ago, I have prospected the area north of Heimschuh several times for corals. My goal was to find some good coral sites. Fossils in the wild are not super-abundant in this formation, but I succeeded to find a few good spots. Corals are by far the most abundant fossil group, bivalves etc. are much rarer. (Note: there is a very large, active quarry for portland cement fabrication in Retznei nearby, that is famous for all kind of marine stuff, incl. Meg teeth and other large vertebrates.) I will present two sites that I have visited again at 10/17/2019, but already also four years ago. One is at Kittenberg in the woods (1), the other one is a small outcrop along a minor road called “Hötzlweg” (2). Continued...- 9 replies

I bought a new old cabinet last winter and spent several months filling it with newly labeled specimens, most of them now stored in jewelry boxes. I took photos of it to show Tim, Fossildude19 and he suggested I post them in the Members Collections section. I followed his suggestion. The collection started in 2011 with a few fossil purchases off a well known public auction site. By the early spring of 2012 I was collecting in the field and the vast majority of my collection was self collected in that manner from sites, primarily in the Northeast and Ohio Valley as well as ones collected on trips to Texas, Germany and out west. There are also some gift specimens that I own thanks to the generosity of a number of friends, most of whom are on the Forum. The top of the cabinet is occupied by miscellaneous specimens, some that wouldn't fit in the drawers, some slated to be in a glass display case I hope to eventually get, and my collection of fossils found in New Jersey just above the Iridium Layer.

Today I was pretty stressed out, but it was also my day off work so I figured what better to do than go out for a hike. Usually around this time of the year Truman Lake's water level drops, and more spots are accessible to hunt for treasures or to journey and site see. I wasn't looking for fossils but instead I was looking for fishing lures, (You'd be amazed how many you can find when the water drops) but I always keep an eye out for fossils as well. I ended up finding a nice little exposure that is usually underwater, and boy it was worth the search. It was about a hour and a half walk to where the exposure was from my car, and I didnt have long to search before the sun set. I probably had a good 40 minutes of sunlight to search and came up with a lot. So much infact, I still have a lot of cleaning to do! Some of the solitary and colonial rugose corals are geodized, or have lovely crystal lining on the inside. I didnt get to take many pictures which I regret, and my few pictures don't do the lovely crystalized coral justice. I suppose I'll share a final photo when I get everything cleaned up.

Hello there! I was inspired by @markjw to check out the Credit River here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician) because where I normally hunt there are typically no corals and I'd love to add a couple to my collection. Consequently, I went out for about an hour this morning before the family got up in order to try my luck, and I'm happy to say that I was successful!!! Based on information provided by @FossilDAWG in other threads here on TFF, I think all of my colonial rugose corals are Favistina calcina - here are photos of three of my specimens: Specimen #1 - side view: Specimen #2 - top and bottom views: Specimen #3 - top and bottom views: more to come...

I visited Etobicoke Creek, and, as usual, the place was packed with fossils. Then I went to Credit River...a park near "The Riverwood Conservancy". At first I was disappointed, but in one place I found 3 little corals that had been packed into a mud path by hiker's boots. Here they are; all approximately 4 cm across.

From the album Hamilton, Ontario Fossils
Paleofavosites asper (d’Orbigny, 1850). Coral squashed on grey shale. Found in the Manitoulin Formation of the Cataract Group on the Niagara Escarpment. Locality is the Devil’s Punchbowl, Stoney Creek, Hamilton, Ontario. Early Silurian. -
July 23,2019 Its been so hot working outside all week that today's fossil hunt in 70 degree temps felt cool. It was quiet in the stream (besides the sound of wildlife) when I got there in the AM and stayed that way all day. I didnt want to disturb the scene with me pounding on rocks so I surface collected and covered a large area of the stream. Along the sides of the stream are glacial erratic boulders, stones, and gravel. The tabulate corals (Chonostegites clappi, Favosites winchelli, Favosites sp.) I pictured in this post were found among these glacial rocks. In one gully off the stream I noticed a large boulder of Waterlime. I have found parts of Eurypterids in these displaced Silurian rocks before. Today I found a partial Eurypterid on one of these boulders but had to leave it where I found it. Too big and way too far to haul back. Happy Collecting, Mikeymig

Hi! Here is a trip report on visiting a locality near Carlin, Nevada (one of our early videos). I'm not sure if what we decided to call "octopus beaks" (see 1:44 and image attached) are the real thing and not just fragments of brachiopods. Perhaps, somebody more knowledgeable can weigh in with the right answer. Thanks in advance!

Hi guys so I have this Hebertella occidentalis specimen I collected yesterday from the Credit River at Streetsville, Mississauga, Ontario, which belongs to the Upper Member of the Georgian Bay Formation. Do these look like predation marks? There are also what appears to some crystallized grains inside these marks and I think they could be some sort of calcite. Sorry for the noisy grain of the image, but I hope this will help.

I got this box of fossil from auction at the low price of £21. The collection is old and dates between 1933 and 1944 . Some of the collection has labels but sadly others are lost or mixed up. Most of the locations are from Yorkshire but there is also Oxfordshire and the midlands. I purchased this lot because of the small collection of corals. The some of the corals have been cut and polished. I did re-polished most of them because they seamed to have a coating to finish the process. There is also some nice plant material from coal seams it is good to get this material from now in the Uk lost localities . Please if anyone can help me fill in the blanks I have added locations I have the labels too, Robin Hoods Bay, Leeds, Wakefield , Whitby , Buckinghamshire and Midlands. I will do a better list of locations when Mrs R gets home because I can’t read some of the hand writing. I think it is a great little collection. Thanks for looking. Cheers Bobby corals 1) 2) 3) 4) 5) 6) 7) 8)

Yesterday the weather in my area hit above the 20 degrees Celsius so I dared myself to go to Streetsville in Mississauga to visit a fossil site I have not been to in 2 years. I now live in Hamilton, Ontario so travelling to Streetsville was intimidating for me using public transit from Hamilton to Streetsville. I have not been to Streetsville by the Credit River ever since I moved from Etobicoke to Hamilton, Ontario and I miss collecting in this vicinity. But I made it. :)) I took pics of exposure sites as these sites are mentioned in one of the literatures describing the Georgian Bay formation. This site exposes the Georgian Bay formation, Upper Member.

This collecting trip was more of a scouting expedition than an actual dig. After the snow and ice have melted, its fun to get out and see whats newly exposed/uncovered. Today we found the usual cast of characters like horn corals, tabulate corals, brachiopods, gastropods, pelecypods, and trilobites. I was mad at myself for not having faith in a trilobite fossil that I found on this trip. It was barely visible in the rock I found it in and I thought it would be incomplete just on how it looked. I started to remove the matrix (hard limey shale) with a hammer and small chisel. The bug popped out of the rock complete and fell on the floor. The trilobite landed on its glabella and some of its shell broke off. I think I found all the pieces but I should have been more careful. After all these years of collecting I should know better. I promised myself to make up for it and that I would find a killer bug this season with some new sites that I have lined up Thanks and Happy Collecting mikeymig

I am back from my trip to morocco. It is a 14 days trip and I got 4 days for fossil hunting. It was so imagine, fossils are everywhere and even though I won't be able to dig, I still get plenty to bring home. Since my guide doesn't speak good English, I am not be able to ask him must so I need help to identify the fossil. On the first day, my guide took me to a place near Erfoud to search for dinosaur teeth. It is very close to the highway. We found a well that the local people dig to get Spinosaur teeth and bone. My husband went down to one but couldn't find anything because the well is new and it is not deep enough. We didn't want to try the deeper one so we decide to bought some spinosaur teeth from the local people there. This tooth is a little over 4.5 inches and I think there are some prepare but I can't tell how much. I also bought 3 smaller teeth and was giving the broken one which I don't know what it is.

I visited a small Paleozoic (Silurian) coral reef in Indiana the other day. No earth-shattering, jaw-dropping discoveries, but it's an interesting spot with dolomitized fossils. Here's a google earth view of the center of the reef. A nice mollusk, if anyone knows what species, let me know. It shattered when I tried to extract it, but I was able to glue it back together as you can see here. Sphaerexochus romingeri cephalon After extraction.. I believe this is a Platyceras: To be continued..

Hello All Today and the next five days I'm on a family trip in the Ardennes. I am close to the region around Hotton. This is known for the many invertebrate fossils that can be found here. I went to a quarry first. I had to get permission from the owners but they gave if I didn't break the obvious rules of fossilhunting in an active quarry. The weather was very nice and the fossils numerous. What else does a fossilhunter want? I searched in an the loose rocks and didn't even had to use my hammer. The ground here is littered with fossil corals. In 5 minutes I found about 20 pieces. I have no Idea of the species yet.

I found these fossils on Jebel Hafeet, Al Ain, UAE. The second rock looks like there is a criniod in it, but is more possibly a type of sponge. The first rock has quite a few things in it, including some type of coral. I would like to know what these really are.

Friends, this time I seek the help of a connoisseur of fossil corals, they are from the Neocomiano (Lower Cretaceous), from a town near Tehuacán, in the State of Puebla (Mexico). The scale is in centimeters. I appreciate your help because although I have dedicated myself to reading the scientific literature of the area, I am an amateur, and many of them are very similar. Of those who have an idea, I put their name for them to say. regards
