Hi, I saw this listing for a Neovenator tooth from the Isle of Wight UK, found in the Wessex Formation, and was just wondering if this tooth could indeed be from Neovenator, or if it is a theropod indet (might be hard to tell since it is only a partial tooth). Striations partially remain on one side and the tooth is about 3cm. Thanks!

A guy is selling this tooth, accordingly a theropod from France, found in Cherves-Richemont quarry, Cherves-de-Cognac. It measures 1,5 cm in length. The seller says it is "allosaurid". I've been looking a bit around for some similiar teeth from the area, as well as species, and I find it a bit hard to find some good articles or pictures to cover this, but from what I can make out of it at this point, it may either be Nuthetes, or perhaps a french Neovenator? I had read recently, that they had found teeth in France, resembling the holotype of Neovenator, so that would make sense with the "allosaurid". There's a lot of disagreement about Nuthetes in general as well, from what I've heard. So what would you guys classify this tooth as? To me the shape does not look much like any dromaeosaurid.

Not very much is published on rare teeth. I'm trying to compile some information so that collectors have something to look at. Might not get them all the answers but its a start. Any discrepancies seen in this info please let me know. If you see anything published that can add to those listed please let me know.

I saw this neovenator tooth for sale. What is the quality/rarity of it? (World class, museum quality, rare, average) it is 2.8cm from Compton bay, the Isle of Wight

The seller says this tooth is from compton bay on the isle of wight, England. Is it rare or high quality.

A seller has offered me this Neovenator tooth Isle of Wight. The tooth is 41mm long and is missing the tip, but the surface of the tooth looks nice. The seller is a British seller who owns a fossil website and has sold Iguanadon, another Neovenator and megalosaurus sp? tooth in the past. Please could you let me know your thoughts on this tooth and if the ID might be correct?

I have never had much luck finding Dionsaur fossils on the isle of wight, the odd rolled bit here and there, this summer i was getting better and spotting the rolled bone better. As well as fossil hunting i love metal detecting on the beaches. Well last weel i was detecting the shingle on a washed out clay area, there was lots of bits of fossil wood that kept catching my eye and i picked some of them up to check.... i found some bullet heads and shrapnel and a few badly beach tumbled coins... the light was fading and i spotted what was either another bit of fossil wood...or maybe bone so i picked it up anyway, it gently scrapped it with my thumb nail and it was hard so not wood.... i looked at it for a short moment and said to my friend who knows nothing about fossils "its looks like a claw" but how many people have picked up something that just looks like a tooth or a claw, he thought it was wood or coal but i have found claws at bouldnor from other animals so i had a good feeling but did not want to get my hopes up. I hope home and posted some photos up for some local hunters to look at, the feed back was looking good but no one dare commit to saying "yer it is a claw". I took it to the local museum the next day and i was glad to hear it was in deed a claw.... there was one other specimin there to compair it to but they are such an un common find there is not much to compair it to. I was told it was likely to be an arm claw because of the curvature it had but at the moment species is unknown.... assumptions are Baryonyx or Neovenator.... i have left it with them in the hope they get a chance to have a good look and see if they come up with anything.... fingers crossed for more info soon.... Happy hunting eveyone!
