Pterygotus Posted February 13, 2019 Share Posted February 13, 2019 I saw this nuthetes destructor tooth for sale from England. I thought it was incredibly rare until I saw some from France. My book tells me only pieces of jaw bone and isolated teeth have been found. My book also tells me that they are found in southern England. Is my book out of date or are the French ones not actually nuthetes destructor? Or is it just the English ones that are rare? 1 Link to comment Share on other sites More sharing options...
gigantoraptor Posted February 13, 2019 Share Posted February 13, 2019 The holotype is from the Lulworth formation in England. Nuthetes is a Dromaeosaurid so I hope that tooth has Dromaeosaurid morphology. It's not sure the French ones are actually Nuthetes sp. This is the holotype: 3 Link to comment Share on other sites More sharing options...

Does that mean nuthetes destructor is incredibly rare, even a 3mm tooth? 1 Link to comment Share on other sites More sharing options...

Jaimin013 Posted February 13, 2019 Share Posted February 13, 2019 I know and trust that the seller knows what to look for when IDing however you still need to request for serration count in order to verify this for yourself! Even then it is a very tiny tooth so it will be difficult to ID. The publication is quite helpful to assist you along the way.

TyBoy Posted February 13, 2019 Share Posted February 13, 2019 Just on the surface the serrations density looks the same on both carina so that would argue against it being a Dromaeosaurid. He needs to do a count however. I also would add that these teeth being a Dromaeosaurid should to be recurved, again dont see that. Please dont trust anyones ID on these rare teeth validate it yourself. 2 Link to comment Share on other sites More sharing options...
The Amateur Paleontologist Posted February 13, 2019 Share Posted February 13, 2019 I'm aware that teeth of Nuthetes-like velociraptorines have been found in the Cretaceous of south-east France... A friend of mine showed me two he had, and they did correspond with the morphology of British Nuthetes teeth.. -Christian Opalised fossils are the best: a wonderful mix between paleontology and mineralogy!

Runner64 Posted February 13, 2019 Share Posted February 13, 2019 The tooth is from the Wealden group and not the Lulworth Formation which Nuthetus is from. It is possible they could be from the same formation (close in age and location) but is not described from there. Keep that in mind. It is a theropod tooth for sure but believe that is the furthest you can go with ID with information at the moment. Link to comment Share on other sites More sharing options...
