2022 Meetings

GA Field trip - Wealden Excursion – Smokejacks
Sunday 26th June 2022 - all day
Leader: Peter Austen and Ed Jarzembowski

This Weald Clay brickpit has yielded a number of important finds over the past four decades. In 1983 Bill Walker, an amateur collector, found a new theropod dinosaur, Baryonyx walkeri, which proved to be crucial to the understanding of the spinosaurs, and on the Geologists’ Association fieldtrip to the site in 2001 a well-preserved partial skeleton of a juvenile iguanodont (Mantellisaurus atherfieldensis) was discovered, and subsequently excavated by the Natural History Museum. Two Baryonyx teeth were also recovered from the Mantellisaurus excavation, suggesting that it may have been scavenged by a Baryonyx. The site is also known for the early flowering plant Bevhalstia pebja(published in 1996), remains of which can still be found. Concretions of sideritic mudstone and siltstone have also yielded numerous insect remains(13 orders) including many new species. Other finds include dinosaur footcasts, remains of pterosaur, fish, crocodile, crustaceans, molluscs and non-angiospermous plants (ferns and cycads, and a Sequoia-type cone). A death-bed assemblage of teleost fish has also been found, which included the first articulated pycnodont fish from the Wealden. More recently a new species of spinicaudatan (clam shrimp) and three new groups of insect have been discovered (earwig, mayfly and ‘stick insect’). During 2016 a small claw, possibly Baryonyx, was recovered,and during 2017, a tooth from a large unidentified theropod. Also, in 2019 a rare parting of crustaceans was found by Mike Webster containing the remains of at least 35 isopods (cymothoidians and idoteids–see Batten 2011, p.120, text-fig.10.3) as well as prawns/shrimps.
