Hello there! A year ago I bought a fossil fish from Brazil at a convention, yet I am unaware of the animals genus. The fossil has a lenght of 37 cm's, and a skull the lenght of 7 cm. 0,7 cm is the average lenght of the individual vertebrae, 39 vertebrae are vsible in the fossil. Skull bones: Maxilla: 4 cm Subopegulum: 4.6 cm (lenght) 3 cm (height) Operculum: 4.6 cm (lenght) 3.5 cm (height) Dentary: 3,2 cm Height of Tail Fin: 7.9 cm Age Location: Presumably Romualdo Formation, based on Matrix and Preservation Aptian-Albian More Pictures in the comments, I am, somehow to dumb to know how to make an image smaller

On the fossil fair last weekend I bought a lot of phosphatised ammonites of the gault clay of France, from Cap Blanc Nez. I got quite a collection of cenomanian ammonites from there, but the albian specimens are rare since the layers aren't accesible any more due to the silting up of the beach. Although they occasionnaly wash up on the beach after storms. during the eighties the layers were still accesible and often prospected by collectors, thus resulting in large quantities of those ammonites in collections of older prospectors. On the fair they sold one of those older collections from this location, lots of boxes full with cenomanian and albian ammonites for 20€ a box. I found 2 boxes with albian material to my liking and after haggeling a little bit over the price I took them home. At first glance most of the specimens were a multitude of Hoplitidea ammonites, but a few hidden gems were in the box like a small but perfect nautilus and a few rarer ammonites. Lots of the specimens need som prepwork, this is what I got prepped or cleaned so far: prepp in progres on a rare Diploceras:

Found this in Comanche Peak limestone formation in Central Texas. I'm thinking Eoradiolites quadratus but not sure if there's enough info to nail down species. Apex to apex measures approximately 1.5 cm for three different samples. I will slowly post more pics of the other specimens, as I reduce photo sizes without losing quality. Thanks for your help.

For years now I have been trying top get a better handle on the various small teeth I find in the Albian age rocks of Central Texas. I have A number of different forms. Finsley, 1996, describes a single genus Uranoplosus as "Lower Cretaceous, Duck Creek/Fort Worth Fms". I have another publication "Lower Vertebrate Faunas of the Trinity Division in North-Central Texas, J.T. Thurmond, 1974, that lists many other genera (not Uranoplosus). But these two associated teeth are a bit different. Note the rather hooked and tapered shape. Anyone ever encountered something similar or can suggest another reference or two? The specimen is from Unit 3, Upper Member of the Glen Rose Formation (Albian) of Kendall County, Texas.

Hey folks maybe you can help me out. Especially the European collectors. Here in Texas we have historically had several species of Tetragramma listed as occurring in the Fredericksburg Group (Albian) that are possibly synonymous. For those of us who collect here in Central Texas there never seemed to be any doubts about what was a Tetragramma malbosii versus a T. taffi. T. taffi are always larger and seem quite distinct from T. malbosii. (see my two examples) But in 2016 William Morgan wrote the Collector's Guide to Texas Cretaceous Echinoids (Schiffer Publ.) and in it he lists T. malbosii as having precedence, suggesting that they are just not as full grown as taffi. He sites the work of Smith & Wright, 1993. I know T. malbosii is found in Europe. What about T. taffi? What does a very large European T. malbosii look like? The one I am using as an example is the largest one I have but it is still not as large as the T. taffi and doesn't have nearly the same number of tubercles in the interamb. Your thoughts, opinions, observations, etc.??? And if anyone can point me to a link or a PDF of the following paper I would greatly appreciate it and could reward with a nice Texas echionoid...

last weekend on our field trip where we usually search for cenomanian ammonites we also found a few phosphate ammonites on the beach that were washed out on the beach from the lower albian layers. most of them were only fragments or encrusted with phosphate, but I managed to prep few of them with very good results: the specimen on the bottom of the picture: Anahoplites planus Hoplites sp. Euhoplites ochetonus

I found this little specimen that I assume is a jaw section a while back when sieving through some matrix. The material that it came from is marine from the toolebuc formation in central Queensland Australia this is cretaceous albian in age. Any input I would be grateful for. The specimen is 4mm on the long so quite small Regards Mike

Hello! I hope to get help from experts to ID some Albian/ Vraconian ammonites. All are from the Zirc Limestone formation, Hungary, Bakony Mts. The locality contains condensed lens of Stoliczkaia dispar & Mortoniceras fallax zones. Thank you in advance! NoID 1 (Clearly not Salaziceras salazecense form, could be some Zuluscaphites/ Metascaphites form? (based on the monography, not Zuluscaphites orycteropusi or helveticus not Metascaphites sholzi or thomasii either) NoID 2 (I thought this some Stoliczkaia juvenile form (???), found this size a few more, no bigger specimens) NoID 3 (Could be Dypoloceras or Hysteroceras???) With Kind Regards

Hello! I hope to get help from experts to ID some Albian gastropods. All are from the Zirc Limestone formation, Hungary, Bakony Mts. All are stone moulds, with some shell fragments. I know, there is little hope to ID the species, but I love to know the genuses at least! The bigger boxes are 6x6cm, the smaller boxes 4x4cm. I can upload separate photos if needed. Please do not mind the last 2 boxes! (Not gastropods) With Kind Regards.

Hello. I found this very weathered ammonite in a stream bed in Northeastern BC, Canada. Geological maps indicate Albian age (Fort St John Group- Shaftsbury). I am wondering if it can be further identified to a species level. Thank you.
