INFORMATION ABOUT THE DORSET WORLD HERITAGE SITE.
The Jurassic coast is UK's first natural world heritage site . It covers 150 km of the coastline from East
Devon to Dorset. It is designed to protect a geologically significant area. The rocks along the stretch
coast are described as "the walk through time" as they span three geological periods back. The coast is
protected with all the land in the world heritage site having legal protection under UK and European
The three geological periods are;
· The Triassic
· The Jurassic
· The cretaceous.
These periods cover from 250 to 65 million years ago. They are popular for their numerous fossils e.g.
the ammonites which are gradually uncovered as the coastline erodes.…read more
The location of the Dorset world heritage site.
The world heritage site extends from the cliff top to the low water mark, between Exmouth in the
east Devon and the southern point of stud land bay in Dorset. It does not include the developed
frontages of the towns of swanage, Weymouth, hyme Regis, Seaton, Sid mouth, Portland port ,and
west bay, all of which are coastal resorts based on the fishing villages.

THE DIFFERENT GEOLOGIC PERIODS IN DETAIL.
· the main features of the site are it's geologic periods which include; Jurassic. Triassic, and cretaceous.
1. The Jurassic.
this refers to a geologic period and system that extends from about 199 to 145.5 million years ago. This
starts from the beginning of the cretaceous. It constitutes of the middle period marked by the major Triassic-
Jurassic extinction event. However the end of the period are defined by carefully selected locations. The
term Jurassic is linked to the Jura mountains.
2 The Triassic.
it is a geologic period that extends from about 250-200 million years ago. This period follows the Permian
and is followed by the Jurassic. Both the start and the end of the period is marked by extinction events. The
extinction event that ended the period has been accurately identified. It began in the start of Permian -
Triassic extinction event which left the earth almost empty. This was also characterised by the dinosaurs' rise
to dominance.…read more
3 The cretaceous.
The Cretaceous is usually noted for being the last portion of the "Age of Dinosaurs", but that does
not mean that new kinds of dinosaurs did not appear then. It is during the Cretaceous that the first
ceratopsian and pachycepalosaurid dinosaurs appeared. Also during this time, we find the first
fossils of many insect groups, modern mammal and bird groups, and the first flowering plants. The
end of the Cretaceous brought the end of many previously successful and
diverse groups of organisms, such as non-avian dinosaurs and ammonites. This
laid open the stage for those groups which had previously taken secondary roles
to come to the forefront. The Cretaceous was thus the time in which life as it
now exists on Earth came together.

has also got the longs sandy beaches. The main attractions at the site include;
· Fossil hunting
· Charmouth heritage site
