30 years a GP, now PhD palaeobiology. Six new dinosaurs for the Isle of Wight. Scientific associate Natural History Museum London. Worried about the destruction of the NHS.
A 125 Ma old log provides a seat. Compton Bay #Isleofwight. Probably Pseudofrenelopsis, an extinct genus of conifer. #FossilFriday

A pliosaur vertebra from the Etches Collection sporting a notochordal boss, an embryonic remnant. These are common in ankylosaur verts but not uncommon in #IsleofWight posterior dorsal and early caudal iguanodontian centra. Rarely reported elsewhere it seems. #FossilFriday

An old photograph of an #IsleofWight Iguanodon fondly known as the ‘Pink Iggy’ when it was mounted above Sandown library. Now remounted in #DinosaurIsleMuseum. #FossilFriday

The 11 cervical vertebrae of #IsleofWight dinosaur Mantellisaurus atherfieldensis are slightly wedge shaped, longer top surface changing to longer bottom surface moving away from the skull. This gives it an S-shaped neck although not with the mobility of the swan’s ~24 cervicals. #FossilFriday

This little book for five bob!! got me into fossils as a 9 year old living in the Midlands on Silurian rocks. Collected corals and ‘lamp shells’ but the prize was always a trilobite.

For #FossilFriday some iguanodontian dorsal vertebrae with ossified tendons which would have formed a crisscross pattern. First appeared Late Jurassic associated with increased mass and quadrupedality. From #IsleofWight in the collections of @nhm-london.bsky.social.

For #FossilFriday a chance to shake hands with the #IsleofWight dinosaur Mantellisaurus atherfieldensis.

For #FossilFriday a posterior view of the braincase of the Early Cretaceous fish-eating spinosaurid dinosaur Baryonyx walkeri. In the collections of @nhm-london.bsky.social. First discovered in Barremian aged Smokejacks brick pit Surrey by collector William Walker in 1983. Time flies!

For #FossilFriday a memory from 9 years ago of my first sight of the @bobnichollsart.bsky.social beautiful and accurate model of an Early Cretaceous parrot faced dinosaur called Psittacosaurus.

Just a reminder that #IsleofWight isn’t all about the Cretaceous but also has terrestrial deposits from the Eocene and Oligocene with some fabulous insect and mammal fossils. For #FossilFriday a coprolite in its matrix. Probably a croc and I’d guess the lower bit came out last. A lovey find.

A polished section of iguanodontian dinosaur jaw #IsleofWight. The detail revealed in a 125 million year old bone by a bit of cut and polish is exquisite. Mostly empty alveolar sockets but the arrow marks an emergent tooth moving in to replace a fractured erupted crown. #FossilFriday.

A recent trip to the #EtchesCollection was rewarded with coming face to face with their enormous pliosaur. A definite candidate for monarch of the Jurassic Kimmeridgian seas 150 million years ago. #FossilFriday.

For #FossilFriday the robust back end of the dentary of a big Iguanodon cf bernissartensis dinosaur found about 100 yrs ago at Sandown #IsleofWight in beds now obscured by sea defences. Nice mahogany brown teeth rather than the island’s usual black.

For #FossilFriday a mass of fragile #IsleofWight spinosaurid caudal vertebrae and chevrons rescued from heavy seas in 2017 on my dining room table. Mapped out, labelled and stabilised and safely transported to #DinosauIsleMuseum where much prep brought together a large part of the tail.

Quite how this dorsal vertebra from #IsleofWight iguanodontian dinosaur Brighstoneus got like this is hard to say. Almost certainly trauma caused a fracture which perhaps was splinted unnaturally by attached tendons so that it healed in this peculiar circular fashion. #FossilFriday

The braincase in left lateral view of Comptonatus chasei, a medium-sized iguanodontian dinosaur from #IsleofWight. Brain would have been ~90 mm long (not bad for a herbivore) and perhaps like birds had a much more complex neural network. #FossilFriday

The little thumb spikes of the #IsleofWight iguandontian dinosaur Comptonatus chasei. These could have been about double the size with a keratin sheath but still seem low grade weapons for an animal a bit under a tonne. #FossilFriday

Opening a door on the fabulous dinosaur collections @nhm-london.bsky.social. As a one time medical doctor who started work before computers I have to admire the hand writing accompanying one of the specimens. An Ornithopsis (Brachiosaurid) vertebra from the #IsleofWight Fox collection. #FossilFriday

The Rev William Fox from #IsleofWight who had more dinosaurs named after him than any British person. Here prepping a sauropod vertebra. He wrote to Richard Owen in 1869 “I cannot leave this place while I have any money left to live on I take such deep interest in hunting old dragons” #FossilFriday

Enjoyable day yesterday working on dinosaur skin @nhm-london.bsky.social. The dinosaur Mantellisaurus atherfieldensis from #IsleofWight was buried whole in lagoonal sediments and is beautifully preserved.
