Correct. It is a Knightia completing your book-end pair. Diplomystus are much more deep bodied (see my avatar image).

Beautiful 61mm Sarcosuchus Imperiator tooth from Niger. Insane colors

[Jaimin013]

Sauropoda indet. tooth
Missour, Boulemane Province,
Fès-Meknès, Morocco (Jurassic)

 

It could be a Atlasaurus tooth but I wouldn't be surprised if it belongs to something else similar to how the Morrison formation which has several sauropods.

Yes, it has found it's place in a nice vintage display case from the sixties.

 I have been looking for the perfect display case and boy oh boy, I think you have it.

 

 I'm always just concerned about the weight of the fossils being held up by glass.

it would appear to be quite as thick as glass, although it would still hold up I think. It would be better to arrange the fossils as in the photo and distribute the weight

Made a trade and received my takeaway from it today:

 

1: Hugmilleria socialis from Pittsford, New York

2: Crinoids from Edwardsville formation Indiana

3: Eldredgeops from Canada

4:  Cerarus from Canada

5: Greenops widderensis from Canada

6: Dipleura dekayi from Western New York

Received today a very cool specimen of Hyphalosaurus from the Yixian formation in Liaoning. It was hard to find a nice 100% original one like this one. Every bone, down to the last vertebrae in the tail, is original. Very happy with it!

 

Species: Hyphalosaurus (formerly known as Sinohydrosaurus)
Location: Liaoning, China
Formation: Yixian Formation

The names Hyphalosaurus lingyuanensis and Sinohydrosaurus lingyuanensis  have an amazing historical coincidence. They were each published simultaneously by two separate Chinese research teams in January 1999. Subsequently they were discovered to be the same specimen: part and counterpart. Hyphalosaurus was finally determined to be the objective senior synonym having priority because the unpublished manuscript was submitted earlier and it had already been cited in the literature.

Thank you very man, it is a second hand i bought to a private.

It's an old showcase, i believe it's oldest than me.

It is so heavy that it was the heck of a thing to put the shelves and doors in my car. It's previous owner didn't tell me it couldn't be taken apart, joyfully he manages a removal company and had a work to do near my house so he put it in one of his truck to bring it to me.

Yes, i chose to put the biggest ones on the wooden bottom for that reason.

The shelfbrackets are thick and go all through the shelves.

I added the most upper shelf afterwards, it's thinner, there's nothing on it for now, but when needed, i'll put on it the tiniest fossils from under.

Camarasaurus lentus
Washakie County, Wyoming
Salt Wash member of the Morrison Formation

 

This tooth was found just a few minutes from Hyattville. You can ID this to a specific level because of the location of where it was found.

 

It was found by a friend and his buddy when they were digging up an Allosaurus skeleton and found this while shovelling.

 

Such a beautiful and chunky tooth.

 

 

 

This tooth was sold to me as a Marshosaurus tooth and is from the Morrison formation but after speaking to @hxmendoza he thinks that this is a juvenile lateral mid to posterior position tooth of an Allosaurus.

 

It appears as though the serration line does curve into the lingual side (the side where the tongue would be and the matrix). It would probably need to be prepped out a bit more to check this.

 

@Anomotodon thinks the same about this being an allosaurid trait but couldn't find evidence of this. He said that some megalosauroids (look at teeth from Niger - huge sample size online) have similar mesial carinae. But I don't think that you can ID any theropod tooth based on one trait alone and so will try to get equipment to measurements of Distal/mesial densities, CHR, CBR.

 

I can see that serrations on the mesial side are more dense than the distal side.

Regardless it's a really cool little fully rooted tooth on the original matrix and wonderful prep work with no restoration. The pics don't do the tooth justice!

The tooth is tiny at about 46 mm - 1.8" and much smaller than both my rooted Allosaurus teeth. Have put next to my fat thumb but is a bit larger in real life than in some of the photos.

 

Here's a vid if you want to have a bit better look at the tooth:  https://gofile.io/d/dW7GBB

Today I received a package with some beautiful sea urchins. I had been looking for Leymiaster eluvialis (vd Ham 1995) for some time. They may not be top specimens, but of course they are not easy to find. I think that is almost no longer the case these days is possible because of the few accesses and all the restrictions and prohibitions.

 

The package contained 2x Leymiaster eluvialis (vd Ham 1995), 1x Cardiaster granulosus (Galdfuss 1829), 1x Cardiaster rutoti (Lambert 1911) and 1x Hemipneustus oculatus (Cotteau 1890)

 

These sea urchins come from the quarries CPL, Haccourt and CBR, Lixhe in Belgium.

Got this rather nice lambeosaurine right maxilla in the mail today.
It's from the Two Medicine formation, Montana. I did a little research and it seems to fit with Hypacrosaurus.

One of the quintessential dinosaurs from my youth (when there were significantly fewer named dinosaurs).  The only thing that could be more iconic would be to have a thumb spike from this species.

Very nice, love it 

[cngodles]

I haven't been able to collect much Late Pennsylvanian material from others, but I like to pick things up to help me understand things I've been finding locally.

 

This Worthenia tabulata from North Texas (Graham Formation?) is both very large and also not morphed dimensionally. The examples I find locally are usually morphed and nowhere near this large.

 

Here is the specimen after I was almost done cleaning it. I cleaned each surface with a scratch brush, but it is heavily encrusted with worms in places.

 

 

Here is the specimen cleaned and coated with ammonium chloride (left side). The specimen on the right is CG-0110, the largest one I've been able to find in over three years of searching locally.

 

CG-0605—Worthenia tabulata

Scale bar = 1 cm.

Love the encrusting, it adds to the story of the piece.

[Mart1980]

Yesterday I received from an old employee of the Sibbergroeve (Bij Valkenburg South-Limburg, the Netherlands) some beautiful pieces from this Margelquarry (Limestone of Emael, Maastrichtian).

 

It included some nice shark teeth like; Palaeohypotodus bronni, Carcharias aff. gracilis, Serratolamna serrata, Cretalamna appendiculata, Pseudocorax affinis, Archaeolamna kopingensis, Squalicorax pristodontus and also a Ganopristis leptodon.

 

 

Also nice marl plates of bivalves Neithea regularis.

 

I was very happy with a piece of a turtle shell in a thick piece of sawn Marlstone.

 

To top it all off, a tooth from the small cusp-tooth mosasaurus Carinodens belgicus.

 

 

I am a very satisfied man .

Oh wow! A Dutch Carinodens-tooth! I don't think I've even ever seen one in real life!

 

You're a very lucky man!

Very nice takeaway... I like the crinoids in particular but they're all showpieces.

I love how you Americans will be fairly specific about locations within the US, but if it's from Canada, it's just 'Canada'.

Apologies, at the time all I knew was "Trilobites from Canada" after getting more details the Eldredgeops rana and Greenops widderensis are from Arkona, Ontario. The Leviceraurus mammilloides is from Lindsay Member, Cobourg Formation, Bowmanville Ontatio.
 

[pachy-pleuro-whatnot-odon]

So, recently got back from abroad to find this awesome collection of new fossils waiting for me. First one's a nothosaur tooth from Winterswijk, quite possibly Nothosaurus cf. marchicus, which I got from @Mart1980. I found some vertebrate fossils in these quarries myself as a teenager, including some nothosaur remains and footprints, but never a tooth. And while at about 8mm this is not the biggest or most impressive nothosaur tooth in my collection, it's really special to me for having come from that location, especially since it's really difficult to go and search there these days.

 

 

 

The next batch consists of some Texas polycotylid remains: a humerus from the Duck Creek Formation of Tarrant County, and two teeth from the Britton Formation at Mansfield. These add very nicely to the partial polycotylid tooth from the Ozan Formation I posted before, and the Dolichorhynchops sp. teeth I've got from Dallas County. I'm quite stoked with them, as plesiosaur remains from Texas are pretty rare.
