Received two very exciting parcels today with a bunch of amazing fossils. The second I will have to post later as I still need to organize, clean, ID everything but this one is much smaller and still very interesting.

This lot consist of three different brachiopods of different ages, from two different places.

The first one may be the one I am most excited about, but I am not sure, I love them all.

 

Can't help, except to say it looks like no Tenticospirifer that I've seen in my limited experience of the genus, but wow, that's three beautiful brachiopods!

Chenanisaurus barbaricus tooth

Maastrichtian Phosphate Mines in the Ouled Abdoun basin, Morocco, North Africa.

Size: 81mm (3.189 inches)

 

Been wanting one of these for ages and finally found this really lovely rooted tooth. Crazy to think that Chenanisaurus is one of the last dinosaurs in Africa before the mass extinction that wiped out the dinosaurs! Mind blowing!

I've seen them come onto the market recently. Must be they've located the right layer for it, although as far as I understand it this all still comes from marine deposits, right? Makes you wonder: did they find the final resting place of one and find the teeth spread out in a single area? Anyway, that specimen of yours is a stunner, as are most teeth in your collection! Beautiful colouring, excellent striations, and a root as a cherry on top! Just: wow!

Thanks! Yes the phosphates represent a marine environment. Most of the fossils known from these beds are therefore marine animals, such as sharks, fish, mosasaurs, and plesiosaurs. It is possible that some animals died and were washed out to sea by rivers and I also read that it is also possible that Chenanisaurus sometimes entered the ocean to swim. Unfortunately, I can't confirm whether they are all found spread in a single area but on a related note last week I was shown a video by a local of him and others digging in the Phosphate beds looking for Mosasaur teeth and other marine fossils and it was a pretty big area so I'm not sure of the scale of the phosphates. They had large machinery to carry away material! I have uploaded the video here so you can see what it is like there! Just incredible to see as you rarely get to see the "behind the scenes" of them looking for material! Here it is --> Streamable Video or https://gofile.io/d/QKKrPj (Same video)

Yeah, I'm well acquainted with the phosphates and have seen similar videos. It's indeed quite astounding how large these quarries are and how extensive the area is that is collected in. A couple of days back I even spoke to someone who had done excavation work in one of the mines and told me that after the machines had scraped off the top layers, they started digging and encountered three complete mosasaurs in what's probably around 30-40m2! The fossil density in those mines is just astounding and incomparable, as far as I'm aware, with any other locality in the north Tethys Ocean (if I get my names right) - irrespective of whether you're talking about deposits in the Low Countries, Britain, Germany or circum-Mediterranean. It's exactly for the size of the Moroccan phosphate deposits that I wonder whether Chenanisaurus isn't restricted to a specific layer or locality that represents a more nearshore or even lagoonal environment. Finding these teeth in the open ocean seems very strange indeed...

Nice teeth, but they aren’t Xiphodolamia. Here’s what Xiphodolamia should look like.

Thanks for the heads up, looking into it now. Might have been misidentified by the dealer, possibly Serratolamna koerti/Tethylamna twiggsensis... koerti seems a better fit I think.

[lesofprimus]

Newest additions this weekend... 

 

A really nice Sperm Whale tooth from the Yorktown Formation in North Carolina 

 

2 very large Galeocerdo cuvier teeth, measuring 2.9 and 2.7 inches... my biggest examples of the species to date

Most all these come from Sidi Chennane bed III.  Attached a paper if your interested in additional reading.  Nice tooth BTW.

This arrived today at noon, there was no information on the sale, but for size, quality, price, I found it interesting.
Solitary horn coral 10 cm long.

 

 

[Misha]

I promised to post my other fossils here and I have finally gotten to take their photos. Haven't got all the IDs but am working through them.

As a quick update to my previous post, I think the mystery Guangxi brachiopod may be Cyrtiopsis sp. possibly davidsoni, I took a look through a number of papers including one discussed C. davidsoni specifically in the neighboring Hunan province which seems very close in overall form as well as the finer structures represented on the shell, but for now it will stay as Cyrtiopsis sp.

 

Before I get to the big lot of fossils here are a few smaller ones I recently received:

 

First, today I got this interesting fish from the Bear Gulch limestone in Montana. It's by no means a perfect fossil but it is still a very nice impression that preserves many interesting features, and I am very happy with it for my first fossil from this formation which I won from a giveaway. I believe this is a Palaeoniscoid, not sure about a further classification as I am not too familiar with much of the fauna here, maybe something like Beagiascus pulcherrimus?

 

The next is a fossil I've wanted to get for a while and finally purchased a bit ago. It's a thin section of the very interesting Rhynie Chert from Scotland. An amazing lower Devonian formation with stunning preservation and this piece was no different. All of the fine detail of the Agalophyton major rhizome is preserved beautifully. On some of the pieces Palaeomyces, fungal cysts can be seen.

 

The final lot was sent to me by @Dean Ruocco, this included mostly very interesting new Hamilton group bivalves, but also some other amazing fossils.

These first few I was told come from the Skaneateles Formation at Cole Hill:

A Nice large bivalve, currently no ID:

A block with multiple bivalves, one especially nice and complete example and a Dipleura cephalon, Actinodesma erectum maybe?

 

This one isn't as complete but I thought the shell details on this one were especially beautiful, Pseudoaviculopecten scabridus?:

Some smaller, loose brachiopods, an Athyris spiriferoides and a Spiriferid I haven't IDd yet.

Some other spiriferids, but these come from the Rochester shale, I might try to prep some out as they look very interesting:

And finally this Eurypterus rempies head from the Fiddler's Green Formation, Bertie Group. Very exciting for me as this is my first Eurypterid fossil and it is incredibly well preserved, even the tiny eyes in the center of the head are visible.

A big thank you to Dean for these, all very exciting additions to my collection. There were a few others but the formation they came from is not known and I may make a separate topic for that.

Thanks for looking!

Lots of very nice acquisitions, I love the Rhynie Chert plant.

But this Rochester Shale piece is of particular interest to me as I'm currently working on Wenlock brachiopods from the Waldron Shale, which is of roughly equivalent age to the Rochester and contains many of the same species or genera.

Good assortment @Misha 

[lesofprimus]

Three new fossil teeth came in yestetday, all pretty decent specimens....

 

A very large Cretoxyrhina mantelli tooth (Ginsu Shark)

A piece of Sharktooth Hill matrix with a small Allodesmus kernensis tooth in it... bummer it cracked tho.

My 3rd largest 1.73" Bone Valley Hemipristis serra

[BirdsAreDinosaurs]

I received some new dinosaur teeth from the Kem Kem beds in the last couple of weeks.

 

The first one is a pretty nicely preserved Spinosaurid tooth, 7 cms long. The carinae appear beaded.

 

 

Here are two small sauropod teeth (tips), approximately 15 mm long. I think the one on the left is a Rebbachisaurid tooth. I am not sure about the one on the right. Might be Titanosaurid?

 

 

The next tooth is an indeterminate theropod tooth (3 cm). These teeth are sometimes identified or sold as Deltadromeus, but we all know that nobody knows what Deltadromeus teeth look like. Some people might not like the patterns on the tooth that are created by plant roots, but I think it looks kind of cool.

 

 

Last but not least, another indeterminate theropod tooth. It is small (13 mm), recurved, there is a visible difference in serration size between the two carinae and the mesial carina is twisted. Might be Dromaeosaurid, but could also be Noasaurid or somethig else.

Wow that is pretty neat, I don't think I recall ever seeing root etchings on Kem Kem teeth before.  This is fairly uncommon, @Troodon?

If you think of the localities where these are found not a lot of plant material around.  I've seen a few but agree its very uncommon.  Pretty neat indeed.

[lesofprimus]

Just received a very nice fully rooted Florida Pleistocene Alligator tooth and two Indonesian Late Pliocene - Early Pleistocene teeth today;

 

Alligator mississippiensis 2.06"

 

Sphyrna mokarran (Great Hammerhead Shark) from the Cisubuh Formation in North Central Java... my 71st different shark species.

 

Trichiurus lepturus (Cutlassfish) from the same location... my 20th different fish species.

Beautiful croc tooth and nice Trichiurus.  However Sphyrna teeth are not serrated that's looks like a Carcharhinus sp.

[Kikokuryu]

I wasn't going to buy that much since I was running out of space, but there was too much stuff I wanted. I probably need a 3rd Fabrikor or Detolf, and that's with 6 shelves per display case. I need to get these labeled up and displayed before something unfortunate happens and things get mixed up. Hopfully I don't get any of the provenance wrong since this is also good extra reference for me if I lose my notes.

 

If anyone wants me to get specific measurements on the dino teeth for reference and stuff, I can try my best. Or make a seprate post and do measurements on every single Jurassic tooth. But I'm honestly not that good at getting good measurments.

 

1. Suchomimus tenerensis - Elrhaz Formation; Gadoufaoua, Niger (Something about Suchomimus I love. I only have like 5 KK Spinosaurids by comparison.)

2. Theropods (Eocarcharia?) - Elrhaz Formation; Gadoufaoua, Niger (Although some of the red-ish ones I feel are Jurassic-ish, but I could be wrong.)

3. Theropoda indet. - Grès supérieurs Formation; Savannakhet Province, Laos

4. Eocarcharia dinops - Elrhaz Formation; Gadoufaoua, Niger

5. Chenanisaurus barbaricus - Couche III; Oued Zem, Morocco

6. Kryptops palaios - Elrhaz Formation; Gadoufaoua, Niger

7. Theropoda indet. - Lourinhã Formation; Lourinhã, Portugal

8. Ichthyovenator laosensis - Grès supérieurs Formation; Savannahkhet Province, Laos

9. Crocodylomorpha indet. - Peterborough Member, Oxford Clay; Dogsthorpe, Peterborough, Cambridgeshire, England

10. Paronychodon caperatus - Hell Creek Formation; Powder River County, Montana, United States

11. Nanotyrannus lancensis (?) - Hell Creek Formation; Garfield County, Montana, United States

12. Nanotyrannus lancensis - Hell Creek Formation; Powder River County, Montana, United States (These were auctioned as Rex, but I'm pretty sure they are Nano.)

13. Gomphotherium angustidens - Gornji Vakuf-Uskoplje, Bosnia and Herzegovina

14. Rhizodus hibberti - Newsham, Northumberland, England

15. Ceratodus kaupii - Sarrebourg, France

16. Jurassic Theropods + Sauropods - Irhazer Group; Marandade, Agadez, Niger (I don't really know where Marandade is supposed to be if anywhere. Looks like the typical Tiouraren preservation, but I'm not super familar with it.)

17. Asteracanthus magnus - Great Oolite Series; Rushden, Northamptonshire, England

18. Mosasauridae indet. - Blufftown Formation; Russell County, Alabama, United States

19. Diplocynodon ungeri - La Guimardière and Pelmer; Noyant-sous-le-Lude, Touraine, France

20. Diplocynodon sp. - Argiles d'lignite du Soissonnais; Verberie, Oise, France (I can never understand French locales so the formation might be completely wrong.)

21. Sagenodus sp. - Archer City Formation; Wichita Falls, Wichita County, Texas, United States

22. Necrolemur antiquus - Quercy Phosphorites Formation; Bach, Lot (Quercy), France

23. Ceratodus phillipsi - Saint-Nicolas-de-Port, France

24. Tissotia tissoti - Abu Roash District, Egypt

25. Partschiceras monestieri - Beraketa, Madagascar

26. Calliphylloceras sp. - Perugia, Italy

27. Phylloceras isotypum - Bereketa, Madagascar

28. Oecoptychius refractus - Deux Sevres, France

29. Castor canadensis - Suwannee River, Dixie County, Florida, United States

30. Diprotodon sp. - Glen Innes District, New South Wales, Australia

31. Arthropleura armata & Lonchopteris rugosa - Upper Silesia Coal Basin; Czerwionka, Rybnik, Poland

32. Jurassic Theropods + Sauropods - Irhazer Group; Effonfone, Agadez, Niger (Similar to the other locale, I don't know where that is, but the preservation seems different. My guess is that mabey the 1st one is Tiouraren while this is Irhazer Shale II.)

33. Ziphodont Crocodylomorph (?) - Irhazer Group; Effonfone, Agadez, Niger

34. Thescelosaurus sp. - Hell Creek Formation; Powder River County, Montana, United States

35. Deinosuchus sp. (?) + Crocodylomorpha indet. - Cape Fear River, Blade County, North Carolina, United States

36. Laevaptychus sp. - Altmühltal Formation; Eichstätt, Bavaria, Germany

37. Platypterygius sp. - Seversk Sandstone; Stary Oskol, Belgorod, Gebiet, Kursk, Russia

38. Abelisauridae indet. - Kem Kem Group; Taouz, Morocco

39. Dipterus valenciennesi - Achanarras Limestone Member; Achanarras Quarry, Caithness, Scotland

More closeups on some of the specimens.

Indeterminate Laos Theropod

I think this is Theropod, but I'm not 100% certain.

Elrhaz Tooth, probably Eocarcharia?

Jurassic Theropod, but I'm not sure what it is

Just got these beautiful dinosaur teeth from a trade with @Flx. Timurlengia and Richardeostesia

[FF7_Yuffie]

Arrived a couple of days ago,  but finally just got round to photographing them. A set of nice microteeth from Hell Creek. The smallest--the 1st pic, is just 1mm. They are all tiny--most under 5mm.

 

I like the speckled one--it's a weird shape. I am wondering if that one could actually be a bird tooth. It definitely stands out among the rest.
