The Rio Puerco Valley was my introduction to fossils. For many years now, I have scoured its Late Cretaceous shales and sandstones in search of ammonites. Somewhere along the way, my fascination with the ornament grew into an investigation of its enviornment. Last week at the New Mexico Geologic Society's Spring meeting (program), I made my first venture into the world of paleontological science. With the help of Dr. Spencer Lucas of the New Mexico Museum of Natural History, I presented a poster/abstract (Foley & Lucas 2017.pdf) exhibiting my ideas. I r- 74 replies

I recently found an echinoid in the Prionocyclyus hyatti ammonite zone of the Upper Cretaceous (Middle Turonian) Semilla Sandstone Member of the Carlile Shale. These creatures are not common and until now... ...I have only found fragments. After a quick clean and some photos, I wonder if there is enough diagnostic material left on this crushed and eroded specimen. scale= 1/4" I do not know much about echinoderms, but I am very much interested in learning

We talk a lot about the aquatic nature of Spinosaurus well here is a dinosaur whose streamlined body is a major adaptation for aquatic animals to move efficiently in the water.

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

I had the opportunity and good fortune to participate in the excavation and preparation of a mosasaur this past year. The specimen was discovered by a new friend, Allison, in a small unnamed stream adjacent to family property in east-central Mississippi (? Prairie Bluff Fm, Upper Cretaceous, Late Maastrichtian).Allison found the first bones in early May and contacted me for help in identifying the bones through a mutual friend. I'm far from an expert, but was able to ID the bones (a radius and vertebra) as mosasaur. She was really excited, since the bones were her first vertebrate fossils othe

Some Austrian upper Cretaceous "Gosau-Fossils" (rudists, Trochactaeon snails) for free
FranzBernhard posted a topic in Member Fossil Trades Bulletin Board
Hello, I would like to give a away some Gosau-fossils from Austria, Styria, for free. Mainly hippuritid rudists, some Trochactaeon snails. I don´t want anything in exchange, shipping is free. If you like, you can donate a small amount to TFF after you have received the fossils, but that´s not obligatory. Please pm me, if you are interested. Thanks. Edit: Closed! Several people have already pointed out their interest in specimens. I am likely to run out of stock . Good thing!! Thanks for all your interest! Franz Bernhard- 3 replies

Classic Trochactaeon and rudist sites at Waaggraben, Hieflau, Styria, Austria (Gosau-Group, Upper Cretaceous)
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, last Saturday (10/09/2021), I visited again some classic fossil sites at Waagraben, Hieflau, northern Styria, Austria with a friend. These sites are known since around 1850, are probably of Coniacian age and belong to the Gosau-group. First, some maps: Overview with location of Waaggraben in Styria, a geological map from Ampferer, 1935 (1 = rudists; 2 = Trochactaeon; 3 = Conglomerate quarry), topo-map, and DEM. These sites are very well known, so no problem to pinpoint them exactly on maps: On the way. We will meet this guy in the backgrou -
I purchased these as Ingenia yanshini which I think became Ajancingenia, which then became and is currently Heyuannia. The formation provided is the Djadochta Formation, but that doesn't seem right since Ingenia/Heyuannia is not found there as far as I've checked. Unfortunately, there isn't provenance other than Mongolia attached to them to say whether they come from the Barun Goyot Formation where Heyuannia yanshini is found. While I'm not necessarily doubting the original ID, I just don't really know. I'm not expecting a positive or diagnostic ID to the genus level, but I wanted

Hey folks, hopefully some of you can help me with this odd thing. It was collected back in 2008 from a small exposure of the Pecan Gap Formation, Taylor Group (Upper Cretaceous) in Austin, Texas. It was found in amongst typical marine fossils such as Exogyra, baculites, bivalves, gastropods and a few scrappy shark teeth. I feel like I have seen this before in a book or museum but I have had no luck looking through my own library. As you can see it has a bone-like outer texture but the shape is unlike any bone I know of. But then I am not a "vertebrate guy." All suggestions welcom

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

Hi all! The Aguja Formation matrix that I ordered from PaleoTex arrived on June 12th, but I decided to wait until school ended before I began the process of searching it. Well, school ended yesterday so I have begun the process today! My 5 pounds of matrix are currently soaking in a solution of baking soda and water (because the matrix arrived "unwashed"), but while stirring up the squishy contents with my hand, I found the following 3 items that I'd like your input on. Item #1: Could this be a ceratopsian spitter tooth??? @Troodon More to follow...

Okay, this may be just wishful thinking, but a girl can hope, right? For your viewing pleasure is an Upper Cretaceous coprolite from the North Sulphur River in Texas, Ozan Formation, Talyor Shale. This little beauty has some unusual fish remains. Any chance this is a caudal fin from a coelacanth? The bones are pretty substantial compared to other fish bones I've seen in coprolites from the area. It does contain scales that are good sized and pretty transparent, with kind of a fingerprint pattern. Obviously, they may not be from the same prey item. Can anyone tell me if these are indeed coelaca

While out in the Puerco, I smacked open a concretion to find an unfamiliar pattern. Any thoughts or ideas are greatly appreciated. The specimen is from the Upper Cretaceous (Turonian) Carlile Shale. It is layered and each layer has this pattern. I currently do not have a measurement but will do so. Thanks for taking a look.

I have seen this item for sale and if genuine it would be a cool thing to add to the collection. But can it be identified as a triceratops collar piece with any certainty? The description says [it is a Triceratops collar fragment from the Hell Creek Formation in Montana, USA].
