The single specimen is known from the Lower Member of the Oxford Clay Formation, along with multiple other dinosaur genera and many other groups of animals, in the biozone of the index fossil "Kosmoceras jason". The Oxford Clay Formation is a marine deposit of southern and middle England, known for the high-quality preservation of some fossils and the large diversity of taxa. Sediments are generally brownish-grey mudstone, organic-rich with plentiful crushed ammonites and bivalves, at most thick. A large diversity of flora can be seen, preserved in the form of pollen and spores. Gymnosperms are present, along with pteridophytes, unidentifiable wood fragments, other intermediate pollen, and miscellaneous organic plant material.
