Hello forum members! With the new Coronavirus raging across the world, I thought it would be nice to start some kind of advent calendar, using my own Squalicorax collection. Everyday I will post one or multiple Squalicorax teeth from one location. Let's see what ends sooner, my collection or the virus outbreak. I will start with the oldest tooth from the Albian substage and end with the teeth from the uppermost substage; the Maastrichtian. The first one is the oldest and also one of the smallest teeth in my collection. Unfortunately it is so sma

ID not certain at all. Very smooth for a Canadoceras. Maybe I should just say 'Pachydiscid'? Exact day of collection is unknown.

Appalachia: Merchantville Fm (Santonian-Campanian) new Hadrosaurids and return of Dryptosauridae
AlexSciChannel posted a topic in Documents
A new paper by Chase Brownstein published today describes two new taxa from the Merchantville Formation of Delaware and New Jersey. A new tyrannosauroid of which metatarsal material was previously described here: https://doi.org/10.7717/peerj.4123 this time a new recovered vert was collected from the same locality likely belonging to the same individual. This thorough analysis of metatarsalian material has given the prescedent to return the tyrannosaur family known as Dryptosauridae which includes Dryptosaurus aquilunguis and the Merchantville taxon. Also described is a new H- 2 replies

Hello, several weeks ago, I presented a rudist recovery "operation" from the Afling-formation of the Gosau-group of Kainach (Upper Cretaceous): Well, the same day I have discovered the rudist zone featured above, I have also discovered a rudist zone about 100-200 m stratigraphically deeper. It is confined to an about 1 m thick, very dark limestone bed rich in various rudist and echinoid remains. The limestone belongs to the Geistthal-formation, considering the limestone is still located within the sequence with some red clastic rocks, suggesting strong terrestrial influence i- 5 replies

Hello! Having discovered some new rudist occurrences in the lower part of the upper Santonian - lower Campanian clastic-marine Afling-formation at Römaskogel hill near Kainach, western Styria, Austria, about 6 weeks ago. Here I would like to present a very specific visit to one of these sites at 05/15/2021. It was aimed to recover some more parts of already known rudists from the outcrop at site #30. Here we go! Approaching Römaskogel, the hill in the middle. Its 1006 m high, the snowy mountain in the background is the Gleinalpe mountain, nearly 2000 m high:

Trochactaeon snails - Kainach, Styria, Austria - 10/10/2020
FranzBernhard posted a topic in Fossil Hunting Trips
Could not resist collecting some more Trochactaeon snails at Breitenbach-11 in Kainach, Styria, Austria last Saturday (10/10/2020). Especially the upper T-bed contains rather well preserved (for the formation, of course ) snails. But always the right amount of weathering is needed (not too much, leads to disintegration of snails; not to less, they will adhere firmly to the rock). Still some potential there. Worked only with a screwdriver, needed only a few very gentle hammer taps. No prepping, just a short brush with a soft tooth brush. For more info about the area, have a look at my- 1 reply

Fossil snails of the genus Trochactaeon from Kainach near Voitsberg, Styria, Austria (Gosau-Group of Kainach, upper Cretaceous) - Summary of this years prospection Introduction Snails of the extinct genus Trochactaeon (formerly part of the genus Actaeonella) are among the most familiar fossils of the upper Cretaceous Gosau-Group of the Austrian Alps. The rather large size of some species (>10 cm), their intriguing spiral pattern in transverse sections and plenty supply, based on many mass occurrence, make them particularly popular. Some well known occurrences in Austria, di

Hello! I have collected quite many specimens with Trochactaeon snails from April to May 2020. They all come from the Upper Santonian to Lower Campanian upper Geistthal-formation or Lower Afling-formation of the Gosau of Kainach in western Styria. Some of the specimens contain abundant black, wavy, "folded", shell fragments. They seem to grow on the Trochactaeon snails in some places. They resemble small oysters in some ways. Unfortunately, I have not found anything conclusive about their identity. I found a pic in a paper of Kollmann (2014), with some somewhat similar, unidentified b

Hello all Up for trade is this set of South-American teeth. It includes 11 Chilean and 4 Peruvian teeth. The C. chubutensis, Isurus desori and Carcharhinus cf. brachyurus (the last three are on the right side) are from Peru. The others (Megachasma pelagios, C. hastalis, Carcharhinus cf. brachyurus, Isurus retroflexus and a fish tooth labelled as dog fish (not sure if correct) and some unidentified teeth. The C. hastalis is just over 2 inch. The Megachasma pelagios is around 2 cm. The C. chubutensis is just under 2 inch and has a crack in the root, but is broken. More precise locati

Hi. Kicking around Mt Tzuhalem yesterday and found a few bits that I'm curious about. The first I think is a gastropod cast but it seems to have spines? The second is a small baculite? Thanks in advance.

04/13/2020: End of my lock-down. Visited a locality with oncoids-oncolites in the Santonian - Lower Campanian Geistthal-formation (59) of the Gosau-basin of Kainach. Locality is near Kreuzwirt south of Geistthal and was told to my by a friend, so I will keep it secret. This is a specimen from block 1. Most of block 1 is still there, I removed only about 2 kg (2 specimens) of the about 40 kg heavy block. Only two more blocks of this material were found, despite really good outcrops just nearby (with alternations of conglomerates, sandstones and siltsones). There should

Almost 2 weeks ago I went with a small group from the rockhound club up to the Vancouver Island Paleontology Museum and the Courtenay & District Museum to see their fossils. Weather was too crummy to do an actual collecting field trip at any place! I guess it's OK to post pics here. I won't post anybody's face. The lighting and some of the display cases themselves presented problems for photography at both places, besides which it was kind of a whirlwind tour, so these shots are the best I could do. I'd say the poor lighting was the worst thing about both places, but we're dealin

This is not a great photo, it was taken after sunset at the site of discovery, and it's a bit dirty. I still need to trim the huge chunk and wash it off, and it now sits in a spot with poor lighting, so this is the best I can do for now, but maybe someone who knows Cretaceous flora can suggest an ID for these leaves based on the general outline? The one on the right especially has 3 clear lobes, and note the stems. Platanus? I have never found this type before, in 9 years of collecting up there.

Fossil hunting in the Geistthal-formation (Santonian - lower Campanian), Gosau basin of Kainach, Styria, Austria
FranzBernhard posted a topic in Fossil Hunting Trips
Fossil hunting in the Santonian - lower Campanian Geistthal-formation of the Gosau basin of Kainach, Eastern Alps (Styria, Austria) As a whole, the Gosau basin of Kainach - St. Bartholomä is not very fossiliferous. In contrast to the St. Bartholomä-formation with its rudists etc., the other, much more extensive formations, especially the very extensive, somewhat tubititic Afling-formation, are generally very poor in fossils. Some are known, eg. ammonites, but their occurrences are rather elusive. One exception - or at least in part - are Trochactaeon snails. They are kn- 9 replies

Hi, a friend of mine told me he found some Placentyceras in a place where the geologic ages go from the Albian to the Turonian-Santonian, but most of the stratas of that place are Cenomanian. I believe this fossil is not an ammonite, but rather an Oyster or a rudist. I mostly think about Requienia or Toucasia. The geologic file mention the name of Toncasia bayleia. Do you know if Toncasia is a synonym of Toucasia and do you think i'm right thinking this is a rudist ? Lenght : 7 centimeters.

I need an ID for this clam. I found this clam in a concretion. it was taken from the Kevin member of the Marias formation. Th Kevin member is listed as Santonian Cretaceous. The location is 5 miles west of Loma Montana.

Here are two teeth from a fairly recently (2011) described Scapanorhynchus species from the Upper Cretaceous Santonian in New Mexico. Scapanorhynchus puercoensis has a dentition similar to S. lewisii and was likely very similar. My son and I do classroom science presentations about fossils and our shark program features Scapanorhynchus. He used the lewisii as the basis for his illustration and now we can actually provide teeth that are a closer match to that than S. texanus likely was. This also allows him to draw S. texanus in a more Sand Tiger like form which we both think it was. I put quit
