Our full livestream from today! Did you catch us on the screen live at ?

Come find us at the Lyme Regis Fossil Festival ! We're at the jubilee pavilion next to the legendary , come see some PALAEOZOIC fossils for a change and ask about how to get involved with our excavations!

They're only little but these tiny actinopterygian (ray finned fish, including the ones you eat!) scales were found by volunteer Ethan during the week thanks to the efforts of the students from University of Birmingham exploring the lower strata of the site. You can see the little 'peg' at the top of the scale and the 'socket' at the bottom where these scales link together like armour. Despite not being amazingly preserved these fossils tell us that vertebrate remains can be fossilised (outside of concretions) on the Fossil Forest site and that small fish lived in the waterways weaving their way between the prehistoric plants. This adds more context or 'colour' to our understanding of the ecosystems preserved here!

We have a student delegation on site this week from learning field techniques and concepts. These guys are the first of over 50 students we'll be hosting at the Fossil Forest this summer!

Fossil Forest volunteers smashing it at so proud of these guys, amazing advocates and representatives! Also, check out the amazing Carboniferous diorama done by using fossils loaned from Brymbo!

Happy flippin 100th to the legend that is ! Obviously a huge inspiration to us all here at the Fossil Forest and Stori Brymbo

The hole that keeps on giving! The mine working uncovered at the bottom of the site continues to spew forth bounties! This we're showing you a *highly suspected* cockroach wing, found by yours truly, from the clay band above the crank coal, while blattoids are common in the carboniferous you should take a minute to check out the scale bar. This bug was an absolute unit! Likely belonging to the archymylacridae or allies it clocks in at 5cm long! That means this roach would be huuuuuge.

Another late drop! Several of our volunteers love scoping out nearby localities for fossil remains and got the jackpot recently with a site that contains loads of disarticulated Upper Carboniferous fish in an ultra fine mudstone. Fish from this period are understudied in general and more so in North Wales, the guys are going through this material with a fine tooth comb to find teeth, scales and bones. Finding, collecting and identifying this material will provide important comparative data for our exploration of the Brymbo marine band this summer, watch this space!

Late drop! Last week our placement student Frey found this little blighter! While it looks superficially like a bivalve (clam) it's actually the carapace of a *bi-valved* crustacean! Luckily muggins here did a lot of research on these guys back in the day so I knew what I was looking at straight away! These cousins of sea-monkeys have been around for over 400 million years and can be found today on every continent except Antarctica. They specialise in 'ephemeral' habitats like puddles or seasonally-occuring ponds. This guy (and a few others of a different species) were found at the bottom of our section in the clay bands indicating a calm, short lived body of water filling with leaves and branches from the surrounding lycopods, perhaps giving these little guys places to hide. Interestingly, many species females can switch part of Thier oviduct to produce s***m to self-fertilise when the population is low! It's amazing how much is preserved here and excited to discover more!
