The stretch of beach between the site of the Wild Coast casino and the
estuary of the Mzamba River in Transkei is locally known as the Fossil
Forest. However, this name is a misnomer, for the large petrified tree
trunks exposed on the beach at low tide are all orientated
horizontally, lack roots and are embedded in rocks which contain a wide
variety of marine fossils. This indicates an ancient marine environment
in which the logs had washed up on the beach or became waterlogged. Low
cliffs on either side of the Mzamba River estuary comprise alternating
hard and soft sediments and continue the section exposed on the beach.
These contain numerous shelly marine fossils which belong to the
Santonian and Campanian Stages of the Cretaceous System of about 75 to
85 million years ago. These rocks and some of the fossils were first
described in 1855 in the Ouanerly Journal of the Geological Society of
London by Captain RJ Garden and WH Baily respectively.
The fossils depicting on the stamps and the commemorative envelope are
from the Mzamba Formation, as these rocks are now collectively referred
to scientifically. They include forms which are now totally extinct,
namely the ammonites, as well as others which have extant
representatives, such as gastropods and bivalves.
Pseudomelania
sutherlandi (Baily, 1855)
This is one of the most common fossil gastropods at Mzamba and was
among the first fossils to be described from this locality.
|
Gaudryceras
denseplicatum (Jimbo, 1894)
This is an ammonite a group of animals that became extinct at the end
of the Cretaceous period, more or less at the same time as the
dinosaurs. This species is known from Transkei, KwaZulu, Madagascar,
Japan and Spain.
|
Neithea
quinquecostata ((J Sowerby, 1814)
This fossil represents a common, scallop-like bivalve with a wide
geographic distribution. |
Pugilina
(Mayerie) acutlcarlnatus (Rennie, 1930)
This is a rather rare fossil gastropod at Mzamba. Commemorative
envelope: Texanites presoutoni (Klinger and Kennedy, 1980) This fossil
is a large ammonite from the basal beds of the Mzamba Formation.
