Aurelius Posted October 6, 2017 Share Posted October 6, 2017 The coast of Somerset is famous for one of the exposures of the Rhaetian Penarth formation, which is better known from Aust, where it is better exposed. It contains many reptile bones, fish scales, shark teeth, fin spines, coprolites, that sort of thing. On my last visit I didn't find any of the blocks which contain large bones, but I did find some containing large numbers of tiny teeth and very small bones. These blocks can be broken down to reveal large quantities of fossils. These teeth are absolutely tiny, some as small as 1mm across and none bigger than 3mm. They can barely be made out by the naked eye, except as a shiny black dot on the rock. 75mp panorama of one of the larger teeth (approx 3mm) I placed this tooth on a magazine to illustrate scale. The letters are standard small print. 4 Link to comment Share on other sites More sharing options...
Ludwigia Posted October 6, 2017 Share Posted October 6, 2017 My guess is you've always got a loupe in your pocket when you go down there. Thanks for sharing! I'll have to keep my eyes peeled next time I'm in the area. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Manticocerasman Posted October 6, 2017 Share Posted October 6, 2017 Oh thats great, I recently got a box of gravel from a now closed location in Belgium from the same age. The material found in that gravel is identical to yours. I’ll try to make some pictures this weekend to compare. 1 growing old is mandatory but growing up is optional.

TqB Posted October 6, 2017 Share Posted October 6, 2017 @Aurelius Lovely material and photos and you've just beaten me to it! - I've got a large slab from Blue Anchor Bay that I picked up decades ago, packed with similar teeth and I recently started photographing them. Most are black but some aren't, like this one - and I'd like to know what the holes are... 1 Tarquin Link to comment Share on other sites More sharing options...
Macrophyseter Posted October 6, 2017 Share Posted October 6, 2017 Tiny, but awesome teeth! If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM! Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 6, 2017 Share Posted October 6, 2017 Excellent photos, Aurelius! Thanks for posting them. Have any of them be identified? I'd love to know what I'm looking at!

ynot Posted October 6, 2017 Share Posted October 6, 2017 Nice finds, thanks for sharing. I too would like to know what they are - beyond shark. Darwin said: " Man sprang from monkeys."

Aurelius Posted October 6, 2017 Author Share Posted October 6, 2017 Thanks for the comments. I have no idea about shark teeth, although there is a book called Fossils of the Rhaetian Penarth Group, which I intend on purchasing when I'm out of my current state of miserable penury.

Anomotodon Posted October 11, 2017 Share Posted October 11, 2017 Great finds! I always wanted to find some cool Triassic teeth. I suppose, flatter and wider crushing teeth belong to Lissodus, and conical teeth with 2-4 cusplets - Rhomphaiodon (Hybodus) minor.

Here is a picture from Welton & Fairish - scyliorhinids have holaulacorhizous roots, unlike hybodonts (I). 1 The Tooth Fairy Link to comment Share on other sites More sharing options...

Manticocerasman Posted October 12, 2017 Share Posted October 12, 2017 also this might help on determinations: https://www.researchgate.net/publication/283030231_Microvertebrates_from_the_classic_Rhaetian_bone_beds_of_Manor_Farm_Quarry_near_Aust_Bristol_UK the flat triangular teeth are Lissodus sp. 3 growing old is mandatory but growing up is optional.

Brittle Star Posted October 12, 2017 Share Posted October 12, 2017 I have that paper, I like the fish teeth in it, ordered a few more papers like it, may get some more ID's. I love researchgate, you can apply for full text and it is free. Really helpful PDF's. Never ask a starfish for directions Link to comment Share on other sites More sharing options...
