Wix bypass (excavations for), WIX, Tendring District, TM148279, Historical site only

Historical site only. Excavations for the A120 Wix bypass in 1997.

-------------------------------------------------

The London Clay Sea was home to a large number of species but perhaps the most curious was the pearly nautilus, an animal with a spiral chambered shell, the descendants of which now live in the southern Pacific and Indian oceans. A very fine fossil nautilus from the London Clay was donated to Colchester Natural History Museum in 1977 and is understood to have been found during the building of the A120.

There is a likely looking cutting at TM 148 279 (south of Wix Lodge) but the museum have no precise locality. Roger Hewitt, a specialist in London Clay nautiloids, has identified it as Euciphocera regule from the London Clay (Division B1 Isselicrinus horizon) (a fragment of a stem of the crinoid Isselicrinus is present in the aperture of the shell).
