Palaeontologist & Curator at Lyme Regis Museum. Mary Anning and early history of palaeontology enthusiast and fanatic about the Lower Jurassic palaeontology & stratigraphy. Palaeontological preparator and conservator (in my spare time).

Finally finished this piece for Lyme Regis Museum . A Green Ammonite Nodule with lots going on and a very 3D aspect. Androgynoceras and Tragophylloceras. Jurassic: Pliensbachian Charmouth Mudstone Formation: Green Ammonite Member Stonebarrow, Charmouth, Dorset

My friend Riccardo found this on Friday and asked me to prep it. Finished it today so he could take it home with him. One of the best Metophioceras I have seen - even with ‘issues’. Normally these have no centre. Metophioceras cf caesar Blue Lias Fm Jurassic: Sinemurian Monmouth Beach, Lyme Regis

Finally prepared a pyrite ammonite I found exactly two weeks ago. Not the common Eteoderoceras obesum but the rarer Eoderoceras bispinigerum. Bed 94. Black Ven Marl Member. Charmouth Mudstone Formation. Jurassic: Sinemurian Foreshore Below Stonebarrow, East of Charmouth, Dorset.

Have prepared one of the early Devonian fish fragments from Cornwall I found on Monday. It revealed a bit of a surprise. All of the specimens I have found from here are pteraspids but this appears to be a piece of a very large traquairaspid. Something new!

The Lands End granite - a megacrystic alkali rich granite. Large complex zoned orthoclase feldspar crystals in a quartz, biotite, orthoclase matrix. Boron in the melt led to tourmaline being a common accessory - often occurring as veins. All in the most beautiful locations

Looking at the Moho (Mohorovičić discontinuity). It’s been 33 years since I last brought Uni of Bristol undergrads to look at the Lizard ophiolite sequence. The far side of the bay are gabbro (oceanic crust) and the near side are serpentine (altered peridotite)

Today I finished prepping another specimen I found about 2 weeks ago. Xipheroceras ammonite about 12cm (4.5in). Not pretty but interesting geologically. The phragmacone is crushed and the centre is encrusted with Semuridia bivalves. Jurassic: Sinemurian: Obtusum Zone: Stellare Subzone.

Just finished preparing this 10.5cm (4.25in) Echioceras ammonite I found at Charmouth 10 days ago. They don’t come much better or bigger than this. Normally found as pyrite steinkerns this one has it’s calcite shell and comes from the Watch Ammonite Stone (Jurassic: Sinemurian: Raricostatum Zone)

Took some old friends for a quick walk at Charmouth yesterday. They are geologists so they didn’t mind. They found some nice pyrite ammonites and I found them a nice pebble with Echioceras ammonites for them to take home. As a bonus I got to see the new landslip - it’s a big one!

Had a good find rummaging through a box of random pamphlets in a local second hand book shop yesterday. An original reprint of ‘Jack’ Callomon’s seminal work on Sexual Dimorphism in Ammonites. He was a chemistry lecturer at UCL but also an ammonite expert in his spare time. £4 well spent 😁

Just submitted a paper on some amazing new material from the Pliensbachian of Dorset tecently acquired Lyme Regis Museum. Here are a few highlights - 2nd complete Panniericidaris known. World’s oldest Crab and world’s oldest Ghost Shrimp.

Tom Pugh and I have had a couple of days down in Lyme Regis! Not beach weather but a relaxing break and a lovely visit to The Lyme Regis Museum where some of Mick’s amazing fossil collection is on display. ❤️
