Smokejacks Quarry.

This will be a trip organised by Kent’s Geologists Group member Peter Austen.Peter will need names and numbers for this event two weeks prior to the trip.

The south east corner of the quarry, where both the juvenile Iguanodon and Baryonyx were found is shown in the picture below.

Smokejacks Quarry

This trip is being run as part of the Kent Geologists’ Group field programme for 2016. This Weald Clay brickpit has yielded a number of important finds over the past three 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 July 2001 a well-preserved partial skeleton of a juvenile iguanodont (Mantellisaurus atherfieldensis) was discovered by Geoff Toye, and subsequently excavated by the Natural History Museum. The Mantellisaurus skeleton was from the same bed as Baryonyx, and two Baryonyx teeth were also recovered from the excavation, suggesting that it may have been scavenged by Baryonyx. The site is also known for the early flowering plant Bevhalstia pebja (published in 1996), remains of which can still be found. The concretions of sideritic ironstone and fine grained calcareous sandstone have also yielded numerous insect remains (10 orders) including many new species. Remains of dinosaur, fish, crocodile, molluscs and non-angiospermous plants (ferns and cycads) can also be found. Recent discoveries have included an arthropod trackway, the first from the Wealden, and new species of crustacean, scorpionfly, leafhopper and beetles. Pterosaur bones, dinosaur footprints and a small cone similar to the present day Sequoia have also been recovered. In 2005 a spectacular death-bed assemblage of teleost fish was found, which included the first articulated pycnodont fish from the Wealden. Also, in 2011 a vertebra and partial jaw of a frog were found, the first recorded from the Upper Weald Clay. During the 2015 field season a new species of spinicaudatan (clam shrimp) was discovered as well as a number of new beetles.

N.B. It is likely that parts of the pit will be flooded – please take care.

The site is now fully fenced and will close at 4.30 p.m.

Cost: There will be a small charge of £2 per person to cover administration for non-Kent Geologists’ Group members.
