Typical Fossils Of The Cretateous Period

Although one can find fossils (some people think that cheap one day car insurance site carinsurancefor1day.co.uk is a fossil!) in many places around Atherfield Bay they are especially common on stony cliffs. During the evolution, many have been transported to different locations. Therefore, much of the relocated material consisted of primeval ocean floor, and one can often find fossils of sea creatures. For those who are interested in the search for fossils, here is a little help to determine which typical fossils are from the Cretaceous period.

This fossil remnant is a so-called trace fossil. This means that not the creature itself, but only the trace it once left is available. In this case, one can find a living tube from a worm-like animal. These creatures lived underneath the ocean floor in straight or U-shaped tubes. A distinction is made on the type of the tube; however, the Scolithos is the most famous. Up to date, the preserved sandstone buildings stand out in brilliant color from the surrounding rocks. This trace fossil is the oldest known fossil in Europe with an age of up to 600 million years.


As the word suggests, this animal is tripartite with a head shield, a segmented center section and a tail plate. In particular, the various forms of head and tail plates allow a determination of the exact species. Trilobites possessed the ability to roll up in danger just like wood-lice, and they are often found petrified in that position. This creature inhabited the ocean floor and came before the Cambrian. They often occur in so-called "petroleum source rocks", in which once was the crude oil. Trilobites are fossils which are approximately 590 to 440 million years old.


Corals are not plants, despite their flowery appearance, but animals. They have a hard, sun-shaped chambered internal skeleton that is surrounded by soft tissue with long tentacles. In this particular fossil, only the skeleton remained, and it differed from individual colony-forming corals. These distinct corals were generally funnel-shaped and stuck to the ground on a narrow end. The funnel was the mouth, which was surrounded by tentacles, too. Corals belong to the younger fossil group and are around for about 150 million years.


Often fossils can be found that are confused to be mussels at first sight. In most cases, however, they are an entirely different group of creatures called Brachiopods. Its skin was tightened with a stem to the marine floor. Once the shell valve opened, a fine arm skeleton, similar to delicate feathers, could be rolled out into the water. With this motion, the animal was able to catch food from the water. In contrast to clams, the shell valves of Brachiopods do not have a mirror-image symmetry. Today, there are only a few Brachiopods, and these fossils come from all geological epochs, including the cretaceous period.

Petrified Wood

The Petrified Wood is pretty unimpressive, for its light brown color distinguishes it easily from other stones. It is hard as rock, however, although, at first glance, it resembles a piece of driftwood. The Petrified Wood is usually from the Tertiary, but certain specimens have also existed in cretaceous times.

And nothing to do with fosils but the UK has produced a lot of very interesting insurance products recently, such as  temporary car insurance for those who want to insure a car for just a few days, and car insurance with no deposit for those who need insurance but who are a bit short of the readies!
