Alderton Hill Quarry (grid reference SP006345) is a 0.34-hectare (0.84-acre) geological Site of Special Scientific Interest in Gloucestershire, notified in 1997.

[1] The site is a significant location for research because of its well preserved Lower Jurassic insect fauna.

There is a range of publications which detail the findings on this site, which include fossil insects.

In April 2024, Swaby et al. published the first comprehensive taxonomic and taphonomic analysis of the entire insect assemblage from Alderton Hill, based on all known museum specimens.

Through comparison with the Lower Jurassic insect fauna of Strawberry Bank, Ilminster, Somerset, this study concluded that the Alderton Hill palaeoentomofauna is the best-preserved and most representative insect assemblage from the Toarcian strata of the UK.
