Okay, in our area we aren't supposed to have Mesozoic layers due to an unconformity....but...is this a rudist?

Rudist hunting (3) in St. Bartholomä, Styria, Austria - 10/23/2018
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, another surface rudist hunt in St. Bartholomä, Styria, Austria (Campanian St. Bartholomä-formation, Gosau-group). This time not in a creek, just wandering in the forest. Two larger rudists were found, lying on the surface. One for me, with partialy preserved upper valve:

Rudist hunting (2) in St. Bartholomä, Styria, Austria - 09/09/2018
FranzBernhard posted a topic in Fossil Hunting Trips
Another rudist hunt in the Campanian of St. Bartholomä, Styria, Austria. For some general information about the area see: http://www.thefossilforum.com/index.php?/topic/86433-rudist-hunting-in-st-bartholomä-styria-austria-13072018/ This time, the largest creek wihin the St. Bartholomä-formation was visited, which is the north-south trending one. Last year, only one rudist was found there. This year - the same result. - Part of the creek from above, its about 5-10 m deep. - Creek. - Steep part of the creek with quite a lot of water and dead wood, but, hey, there is a rudist, just to the left of the red x! - Rudist as found, pocket knife is 9 cm long. To be continued...

Rudist hunting in St. Bartholomä, Styria, Austria - 13/07/2018
FranzBernhard posted a topic in Fossil Hunting Trips
Heavy rains in Styria, Austria, have overturned many creek beds. So this is a good time for fossil hunting, e.g. for rudists in St. Bartholomä: View of the hunting area from Pleschkogel mountain (1063 m) toward St. Bartholomä with Kreuzegg and Kalchberg, distance about 8 km. Note the conspicuous church of St. Bartholomä, just below Kreuzegg. View is nearly southward, in the far background the Pohorje mountains in Slovenia. Photo taken 07/07/2018.

I had the day off yesterday and headed out to the North Sulfur River. Found absolutely nothing of note except lots of wild hog wallows, lots of spiders, the usual petrified wood and a couple Cretaceous bone chips. Had another one of my stupidity inspirered adventures with the heat. It was 100 out there and to make it worse the water was also 100. Made it out in one red bug laden piece. Recovered, ate lunch and glutton for punishment that I am headed back out at a much easier access point. While I was there I found something, which I don’t know what it is. The only thing I can possibly imagine it could be would be a rudist. There are 2 varieties of rudist in the NSR. I believe this is a colony of Sauvagesia belti rudist, but I’ve never seen one. I believe I was in the Pecan Gap Chalk overlain by the Ozan. The concretion in question I believe to be from the Ozan since it was not in situ, but in a gravel bar. This is the concretion as I found it. Only 1/3 was exposed. It’s about 8 x 7 inches long and wide and 3.5 at its thickest. It has an Inoceramus clam on the righ. I have not learned my species, but I think this is the I. balticus. The other species noted there is an I. aff. Barbini. But that is not the key item for ID. There is a hollow chamber in the middle that has shell material inside. I’m working on trying to remove matrix from it so it is a mess right now. This is a top side view. This is a bottom side view. There are the ends of 4 individual organism in view in the pic below. All seem to have been basically tubular and average approximately 4- 5 inches long from what I can tell. In the top of the pic there are 2 perpendicular to each other. One overlaying the other. Bottom of pic are 2 running parallel to each other. I was cleaning the big one on the bottom and came upon the end of another laying on top of it. All 4 have the remnants of nacre on them. I think there are 5 individuals here. There is a 5th on the bottom of the 2 on the right. This is one with the full length in view of what is present at least. It is 5 inches long. This is what got me excited after I picked it up and rinsed it off. It is that beautiful dragon skin quality found in nacre. This is on the end of one of the individuals. I believe there are more than 12 in the conglomerate. I’m Still uncovering stuff though. Any thoughts as to what they may be would be be greatly appreciated. Thanks, Kim

One of my students found this near Jacobia Texas and would like it identified if possible. I have more pictures of it on the forum's Facebook page.

I happened upon this forum and I am happy to share what I have found and have learned. I'm always interested in learning more and seeing what you all have to share. I am sending photos of a fine detailed Rudist . It was found in eastern Travis County. I have seen many rudist sections and remnants but this one was the best ever found and that also according to invertebrate paleontology Department of UT who Of course wanted it donated to th University.

Hi, This is a detached piece I found in a mountain torrent. Campanian-maastrichtian strata, SE Pyrenees. My guess is genus Vaccinites, mainly due to the polygonal-shaped pores on the upper valve (which has big diameter: around 15 cm.) Lower valve is conical, geniculate and broken before its end, allowing its pillars and ligament ridge to show. Can anyone confirm the genus and, if possible, identify the species? The most common species in the zone is Vaccinites archiaci.

Hi everyone, I found those pieces in a Campanian-maastrichtian limestone strata in SE Pyrenees (Catalonia, Spain) My ID guess is genus Lapeirousia, maybe Lapeirousia jouanneti or Lapeirousia crateriformis, species easily found in Aquitaine, France., mainly due to its characteristic pseudopillars. Thanks,

Hi, I live in an area where there are plenty of upper cretaceous rudist-coral reefs to study and for the time being my interest is focused on them. I’m an amateur, not a sound paleontologist. Hope to learn a lot together.

Hello, I caused a little bit of excitement at the DPS Fossilmania last month when I pulled this out. After going from person to person, the consensus was rudist. However, I wanted to get a few more opinions and see if possibly, we can get more specific. Found in Bell County, TX near Lake Belton. Possibly transported, so not sure of the formation, but definitely Cretaceous. Thanks!

Hello! I am currently looking for the rudists of the Upper Cretaceous Gosau basin of Kainach, Styria, Austria, around St. Bartholomae. So far, I have found one determinable specimen. I think, it could be Vaccinites vesiculosus (Woodward 1855). From this area, beside other rudists, Hippurites styriacus Hilber 1902, Hippurites carinthiacus Redlich 1899 and Hippirutes oppeli santoniensis Kühn 1954 are described in the literature, which seem to be all synonyms of V. vesiculosus, according to various sources. The first photo shows the outer surface of the specimen, which is not very distinctive. Height of the specimen is 13 cm, maximum diameter about 7 cm. A saw cut is indicated by a green arrow. The second picture shows the two polished, cut surfaces of the "rock". The diamater of the large rudist is 7 cm, it seems to be intergrown with a Radiolites sp. and there is also a small Hippurites sp. nearby. The third picture is an enlargement of the V. vesiculosus in question. What do you think, could my determination as V. v. be correct? Thank you very much for your help! Franz Bernhard Picture 2

So, I've recently came back with a relatively large haul of early Maastrichtian marine fossils, presumably deposited as debris from a nearby reef. Here are some of the ones I'm curious about: Let's start off with this solitary coral: Based on pictures on the internet, I get the feeling that it might be a Cunnolites sp. Next up is what is presumably some type of algae: Next, this... thing. I honestly have no idea what it could be - rudist? gastropod? EDIT: Informed that it is a gastropod. Now, these things. I have a very strong hunch that they're rudists, but I need both confirmation and, if possible, some family/genus level identification. Now, this one stands out to me as it is much flatter/more ellipsoidal than the rest AND seems to have a different texture: What family/genus could this bivalve be? It seems really familiar: And finally, this. I have no idea what it could be. A trace fossil? Some kind of algae? Some rock formation?

So, I've got this early Maastrichtean rudist, and I'm looking for a good way to get it in a presentable shape, preferably without having to use expensive equipment. The matrix is limestone, though not soft enough to be simply peeled away with a brush. I'm not sure whether using vinegar would be a smart idea - I have a feeling that it would damage the fossil. Also, what would be the best way to reattach the two separate parts together? I thank anyone giving input in advance.

Hello! These pictures are in situ of a fossil locality I discoveted in Argolis area of Greece. The age is Upper Cretaceus (Cenomanian). I believe that there are lots of Rudists fossils in sections, the ones with circular shapes. But between them there are lots of objects similar to "fish spines" as seen on the below pictures. Are they also sections of Rudists but sliced vertically? Thank you in advance!

I spotted an interesting fossil within a rudist reef of edwards group limestone near ozona, Texas Cretaceous Albian. This outcrop appears to be dolomitized Left of the chapstick cap. Thanks, George

This two fossils were laying for about 1 year in my room and i dont know what i should do with them. The first step would be to know what specimen they are ... I found both in the upper Cretaceous from Gosau (Austria). The first one looks like an heteromorph ammonite but i dont if you can find them in Gosau .... I also found some more ammonites in the matrix ... arent ammonites very rare in Gosau ? Its about 7 cm long ... (maybe there are two ammonites ? I am confused ) And here is the second one ... First i thought that its a coral but i dont think its something like that .... Maybe a rudist ? Its 6.4 cm long and very massive:. Thanks for your help !

Hi,i found this rudist,but im not shure what crystall is it.is it quartz?

While waiting to go on a fossil hunting trip of my own to a different site in the upcoming months, I have received three fossils that I am now trying to ID. I didn't have much success, so I would like to ask the forums for assistance. All three fossils are upper Miocene(Tortonian) in age, and were originally deposited in the southern slopes of the Pannonian sea. The first fossil is obviously a bivalve, but I can't decide whether it is a cockle or scallop, since the rear parts of the fossil are missing. Is there any other characteristics beside the presence of auricles to determine which one of the two families it is(or if is something else entirely)? The fossil is 4cm long(from the front of the shell to the opposite part of the rock). Also, on the rear part of the rock, there is a small tube slightly visible in the lower central part of the rock, around 2mm in diameter - the siphon? If it is a siphon, does it mean that the fossil is a cockle(AFAIK scallops don't use siphons)? The second fossil is a scleractinian, I think, but I have no idea about anything lower on the taxonomic tree. Is there any way to narrow it a bit more down, at least to the suborder or family level? Or to infer the structure of the living coral colony(whether it was massive, frondose, etc.). Also, it appears as if something had encrusted the surface of the coral, but I am unsure if it is an actual encruster(bryozoan or algae), or just deceitful ordinary rock. Length of the fossil is around 4cm. The third fossil is also the most damaged. I'm pretty sure it's a bivalve fragment, but not much beyond that. Two things I've noticed: 1. It seems pretty large for a bivalve. It is 5cm long, but it is obviously only a small fragment of what was once a much larger shell. Either that, or the ribs are extremely thick. 2. The underside of the fossil has several patches of what I am 90% sure is an encrusting bryozoan(I can take a picture if needed). The way I interpreted it, the shell got disarticulated after death due to waves/currents(the matrix itself is fairly coarse sandstone, if I am correct, so the environment must have been fairly high-energy) and the underside was colonized by bryozoans. This means that the living bivalve lived on the surface, rather than buried within the substrate, which might help a bit with ID. Input would be highly appreciated.

hello,is that a rudist colony,or somthing else?tnx
