Undescribed shark from Toolebuc Formation, Australia. Albian in age. This tooth possesses folds along the enamel on both sides of the tooth (hard to see in photos), resembling those on Cretodus.-

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.

A - lateral; B, C, D - anteriors. Anterior teeth have typical of Heterodontus V-shaped root and marked cutting edge. Unlike H. canaliculatus anteriors, anteriors of ‘H.’ upnikensis have more convex labial side (so that cutting edge is situated in the middle of the lateral surface) and no lateral cusplets. Crown generally widens near the base, so most teeth have regular triangle shape of a labial face. Teeth located closer to symphysis display more mesiodistally compressed crowns. Enamel is smooth on both faces. Lateral teeth are also different from H. canaliculatus: they have lower and shorter central occlusal ridge and lateral ridges are highly anostomosed on both sides, so that complete tooth ornamentation has a net-like appearance. ‘Heterodontus’ upnikensis is an enigmatic species. No associated tooth set has been found yet, consequently it is impossible to tell that a given set of laterals actually belong to ‘H.’ upnikensis. There is a possibility that lateral teeth described here as ‘H.’ upnikensis here belong to another Heterodontus species not represented by anteriors in Kanev collection. They were assigned to this species because there is generally some degree of tooth plan similarity between anteriors and laterals of the same species. Laterals described here have: 1) relatively weak and short central occlusal ridge; this trait is similar to ‘H.’ upnikensis shorter cutting edge because of lateral cusplet absence; 2) more bilateraly symmetrical crown shape and ornamentation across the central occlusal ridge than in H. canaliculatus; this feature is analogous to relatively equal thickness of labial and lingual face on ‘H.’ upnikensis anterior teeth. Also, anteriors of ‘H.’ upnikensis are a lot more common in studied locations than H. canaliculatus, and the same trend applies to two found Heterodontus lateral teeth morphotypes with H. canaliculatus teeth being a lot scarcer.
