Will take this for you when I'm back home. I'm off to Isle of Wight tomorrow to do some fossil collecting so will take them on my return on Monday. Cheers

So per 5 mm:

 

Large: 11 - Distal, 12 - Mesial
Small: 13 - Distal, 15 - Mesial

 

Let me know if you need anything else.

So last weekend I had an incredible time first time fossil hunting in Isle of Wight with @Haravex! 

 

Thanks alot for being so kind and awesome and showing me the ways and teaching me where to look and what to look out for, what is needed to extract, things to be aware of etc!

 

Here are some of my fossils finds. The highlight find was an Iguanodont spitter tooth (Second pic)! Also found three really nice Lepidotes sp. fish teeth (See 3rd pic left), Gastrolith, fish scales, a limpet shell and saw alot of bone material and other cool things! 

 

Lepidotes is an extinct genus of Mesozoic ray-finned fish which have been found in Jurassic and Cretaceous rocks worldwide. Inhabiting both freshwater lakes and shallow seas, Lepidotes was typically about 12 in long. The body was covered with thick, enamelled scales. Batteries of peg-like teeth enabled Lepidotes to crush the shells of its molluscan prey. Fossil examples of these teeth were collected in medieval times as 'toadstones', claimed to be found within the heads of toads and to have magical powers against poisoning. (See 3rd pic showing the three that I found and a section full of teeth on top right from a publication belonging to Lepidotes maximus).

 

I came across a largish piece of fractured Gastrolith embedded in the matrix which had to be extracted. I think I'll try to piece this back together soon as there aren't too many pieces from what was salvaged.

 

Finally also got to see some dinosaur footprints on my walk along the coast from Compton Bay to Brook Bay to Brighstone Bay. Also got to visit sights such as the Needles (a row of three stacks of chalk that rise about 30m out of the sea).

 

I hope to go back to IOW again soon but when it's raining as I am curious as to what the weather could expose as last weekend was really sunny!

It's been way too long since I last was at the Isle of Wight now probably seven years ago, but there's always something great to be found there! Just too bad most of it isn't marine reptile (although I've some to understand that this just depends on the layers you search in), so that other places have been taking priority for me... Anyway, great finds! And, yeah, searching IoW is very infectious

Received these three dinosaur teeth from Isle of Wight UK today.

 

First is a Hypsilophodon tooth then two Sauropod teeth - one that is just the tip and the other which is more complete but fairly worn but has some enamel present.

 

I've been looking for these teeth for some time now and a sauropod for ages so glad I finally have two!

Received two new dinosaur fossils and blue fluorite.

 

The first is a Two Medicine formation caudal vertebrae from a Hadrosaur. It originates from Teton County in Montana from a quarry near Bynum. There are multiple in this Formation so not able to assign to a particular dinosaur. It's a really large vert! The spine broke into the original 3 pieces that were glued back together by seller so I had to remove the old glue with acetone and a xacto knife and rejoin with new glue.

 

Second is a rooted Ceratopsian tooth from Hell Creek Formation. The digger's prepper said that it has the longest root that he has seen in 30+ years! The tooth is 76mm so just under 3 inches.

 

The blue flourite with Druzy matrix is from Hunan Province in China.

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!

Ceratosaurid tooth

Isalo IIIb formation

Madagascar

 

My first fossil in ages. It's got the diagnostic grooves!

 

[Jaimin013]

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.

[Jaimin013]

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.

The serrations on the mesial side are more dense than the distal side.

 

Speaking to someone else, 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.

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

Sauropoda indet. tooth

Missour, Boulemane Province,

Fès-Meknès, Morocco (Jurassic)

 

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

Very nice tooth but yes like most other Jurassic exposures throughout the world identification of isolated sauropod teeth can be difficult because of the diversity found at these locations

Majungasaurus tooth

Madagascar

Maevarano Formation, Mahajanga Province

 

Received this tooth this week. It is a pretty large crown and has lovely distal and mesial serrations. I love the brown shade of the enamel, it is super smooth! I have another Madagascan theropod tooth that I've posted about previously, but I'm not entirely sure what it is!

Rebbachisauridae sauropod tooth

Isle of Wight, UK

31mm

 

I received this rare sauropod tooth on the matrix from the IOW yesterday! My first more complete sauropod tooth. I have 2 partials but not one this complete! 

[Jaimin013]

Suchomimus tooth

Niger

~57-58mm (2.638-2.677 inches) in length!

 

Received this rooted tooth last week. It's now my second largest Spinosaurid tooth after my Spinosaur tooth from Morocco and bigger than my recent Baryonyx that's about 55mm. Lovely distal and mesial serrations on both sides.

 

 

I've been speaking to a friend recently who thinks based off claws that he has that it may well be potentially larger than Spinosaurus! The holotype isn't a grown adult. Yesterday, I saw some of their claws including one that is 33cm along the straight line, they are huge trust me! Much larger than any Spinosaurus claws from Morroco or the well known Baryonyx claw from the UK.

Ichthyosaur tooth (Likely Stenopterygius sp.)

Posidonia Shale

Holzmaden

Germany (Early Jurassic)

 

Received this small 185 million year old rooted tooth this week. The tooth doesn't match Temnodontosaurus and the other Ichthyosaur from here is Eurhynosaurus longirostris but you'd expect to see horizontal banding and pinching towards the tooth apex which doesn't seem to be the case for this tooth.

 

[Jaimin013]

Baryonchid tooth

Isle of Wight, UK

55mm (2.165 inches)

 

Received this incredible tooth yesterday. Didn't think I could find one that is larger and wider than my current larger one (I've not posted that on here) but this new one is! Last pic compares to my other larger tooth.

 

The colours on this tooth are very unique and a really chunky tooth! The part near the root area of the tooth has these cool enamel folds.

 

I saw this tooth 5 years ago and have always wanted it so glad I finally do!

Two fully rooted Madagascan sauropod dinosaur teeth

 

[Jaimin013]

Diprotodon optatum upper incisor tooth

Reddestone Creek (Pleistocene)

Glen Innes

New South Wales, Australia

 

This fossil has recent export permissions from the Australian government. Super excited to be able to have the opportunity to acquire a fossil like this.

 

For anyone who isn't familiar with Diprotodon it is the largest marsupial known & the last of the extinct, herbivorous diprotodontids. It was the first fossil mammal named from Australia (Owen 1838) & one of the most well-known of the megafauna. It was widespread across Australia when the first indigenous people arrived, co-existing with them for thousands of years before becoming extinct around 25,000 yrs ago.

 

 

Received these incredible Australia dollar dinosaur collection coins with it too!
