FF7_Yuffie Posted November 18, 2020 Share Posted November 18, 2020 One of my tiniest dino teeth. An ornithopod from Hastings UK. Not the best photo, but its got nice detail to it. Link to comment Share on other sites More sharing options...

It is really small, but with the length of 2.5 mm still larger than the Hypsilophodontidae tooth, which measures only 1.5 mm – no fossils for the showcase.

-Andy- Posted November 20, 2020 Share Posted November 20, 2020 One of those indeterminate theropod tooth from the early Cretaceous Cherves-Richemont Quarry (145.5 - 140.2 mya) of Cherves-de-Cognac, France I was told this could be an Allosauroid indet. but I have no idea how to determine its ID. I guess if we used process of elimination it could also a Megalosauroid indet. 3 Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...

That has to be the smallest dinosaur tooth I’ve ever seen then! Very cool 1 Link to comment Share on other sites More sharing options...

Very cool I have seen pictures of even smaller teeth, painstaking work to look for them! The teeth from the Jurassic of Morocco are really nice, by the way!

I guess if we used process of elimination it could also a Megalosauroid indet. I don't really understand these theropod teeth from Cherves. All I had seen are like this one, very finely serrated, lingually inclined and sometimes with enamel fluting which makes me think they could be basal Spinosaurids? Here is a very Spinosaurid (Baryonychine?)-like tooth I had. Flutting, very fine serrations, not very laterally compressed, little distal carina curvature - pretty typical of early spinosaurids. Cherves locality is Earliest Cretaceous (Berriasian), ~20 my older than Baryonyx, so it is logical to assume that spinosaurid teeth at that point were not entirely specialized yet and still had traits of typical megalosaurids. However, teeth like yours - the ones without any fluting I am not sure about. Serrations and almost all other features are very similar to the potential spino teeth but I am not sure if lack of fluting can be explained by positional variation or whether it is diagnostic. I can't find any information about spinosaurids from the Berriasian OR about theropods from Cherves. There is a Late Jurassic Ostafrikasaurus, but I believe it is currently considered a ceratosaur. Who knows, maybe in 5 years these teeth will turn out to be from Notosuchian crocs. 1 The Tooth Fairy Link to comment Share on other sites More sharing options...

Interesting I have heard several suggestions on croc on these teeth too. Unfortunately, there is just not a lot of info out right now to make a decision. Love both teeth you posted and I can certainly see some affinities to a basal spinosaurid in your first tooth. Link to comment Share on other sites More sharing options...

I guess if we used process of elimination it could also a Megalosauroid indet. I've always thought this morphology was an Allosaurus type tooth. I just never took the time to confirm it but decided to do so with the characteristics off of one of the teeth in my collection. Matches your pretty closely. The best person to comment on it was C. Hendrickx so I emailed him. These are his comments: "Yes, that looks like an Allosaurus/allosaurid type of tooth to me. Only a phylogenetic analysis can confirm this though but that's what I would say. And it's not surprising given that the fossiliferous deposits of Cherves-de-Cognac are Berriasian and we have allosaurids in the Tithonian of the Iberian Peninsula. So, pretty logical to me."

Suchomimus Posted November 28, 2020 Share Posted November 28, 2020 This weekend I want to show you a sauropod tooth which was found in western France – that is what I was told where it is from, at least. Maybe someone can help me regarding an ID or a provenance for this tooth. It is from my very early, naive days of collecting – feel free to let me know what you do think about it: 1 Link to comment Share on other sites More sharing options...

Suggest you contact François Escuillié (Eldonia) who might be a good source and is familar with and published on French material. Nice tooth BTW. 1 Link to comment Share on other sites More sharing options...

paulyb135 Posted November 30, 2020 Share Posted November 30, 2020 I will contribute with this unique multi coloured Baryonyx tooth which is easily one of my favourite teeth I own.
