Cretaceous
GEOGRAPHY AND CLIMATE: Seas flood half the land, Great thickness of
chalk, single-celled animals laid down. Land masses
begin to move towards their present positions. Climate mild without
extremes.
TERRESTRIAL ANIMAL LIFE: Advanced dinosaurs such as duck-bills. Turtles,
snakes,salamanders. Gulls and wading birds. Opossums & other mammals.
All dinosaurs and many other large reptiles extinct by the end of
the period.
PLANT LIFE: Gymnosperms, sequoias and cypresses. Flowering plants appear,
magnolias and oaks.
SEA LIFE: Plankton, coral reefs, rudists, ammonites, calcareous algae.
Marine reptiles and ammonites extinct by the end of the period. |
Pleistocene
GEOGRAPHY AND CLIMATE: Ice ages cover Northern lands, sea level falls
TERRESTRIAL ANIMAL LIFE: Woolly mammoths and rhinos, saber toothed cats.
cave lions. Giant marsupials in Australia. Human hunting skills
develop, many large mammals disappear.

Geological Guide to Studland Bay
At the southern end of the bay, the upper chalk is exposed. This is of the Mucronata Zone from the Campanian stage. Above the chalk is the Reading Formation from the Eocene period, this is mostly pale grey sands.
The Northern end of the bay begins with the London Clay Formation, although this is poorly exposed and overgrown. The Redend Sandstone from the Poole Formation is well exposed up to Redend Point.
At Redend Point, the Pipe Clay Series yields plant remains. This is also part o the Poole Formation of Eocene age.
