Fossils from Norfolk, Yorkshire, Dorset and around the world.
About us
Welcome to Belemnite Bob's. I am a local man from Norfolk who has a passion for fossils and wants to share my finds and hopefully inspire others in this fascinating world.
I have been fossil hunting for around 5 years and every time I find a fossil it gives me great pleasure as I might be the first person in thousands or even 100's of millions years to first gaze at the fossil.
I want to use this site to sell some items that I have found and to help educate in different aspects of fossils.
I mainly fossil hunt in various areas of the North Norfolk coast but have visited North Yorkshire and Dorset. All lovely locations as an individual or as a family.
Any queries please contact belemnitebobs@outlook.com
Different Fossils
This section is where you will find useful information about fossils and stones.
Fossilisation
Fossilisation is the process of where animals or plants become petrified in state.
As layers of sediment gradually increase on top of the specimen they begin to compact and then become rocks themselves.
Water then flows through the sediment and water minerals then replace the organic matter of the animal/plant which then becomes a fossil.
What is chalk?
Chalk is a sedimentary rock. Chalk is formed when microscopic life forms such as plankton and shells settle on the sea bed. They then become compressed and become chalk.
Chalk is roughly 61 to 100 million years old. In the UK and around Europe we have large chalks seabeds. On the Norfolk coast our chalk bed is about 200 miles long. It is about 20 metres deep.
Belemnites
Belemnites also known as 'fossil bullets' because of their bullet shape are an extinct type of squid. Unlike modern squid they had a internal skeleton that made up the cone.
They lived through the Triassic to the Cretaceous period meaning that a fossil could be 66 - 200 million years old!!
Sponge fossils
Sponges are a very old life form. Primarily the skeletons are preserved. Sponges generally do not move and they feed by filtering water through them and syphoning out the micro organisms to feed.
Sponges although a simple life form give an indication of early life and are some of the oldest fossils to be found.
Sea Urchin Fossils
Sea Urchins when fossilised are also called Echinoids. They are a very old animal. Some fossils go back to 450 million years of age.
They are easily defined as they always have 5 lines of spins going up to a central point. Here in Norfolk they are pretty common and they come in different shapes and sizes the most common seem to be dome shaped but different species do come in doughnut shapes, heart shaped and in many different conditions.
Brachiopods
Brachiopods are fosiilised creatures that are best described as shellfish. They are a very old animal that still live today.
They have been around since the Cambrian period which was 487 - 538 million years ago. They are a creature that have two halves of a shell. Like modern animals they are able to open to feed and to close for protection. These are quiet common fossils that can be found around they uk.
Coral
Fossilised Coral can be found in Norfolk and around the UK.
I have managed to find a few pieces on my travels in Norfolk. They come in different shapes and sizes. These can be found in the chalk and generally laying about on the beach.
They show how much diversity for life that used to be here in ancient times.
Bone/Antler
Fossilised bone and Antler can be found around the UK. from a wide variety of animals.
In Norfolk you can find all sorts of different pieces alot are indeterminable pieces but you can find large pieces that could come from mammoth or the various deer species that used to live here. You can even find bones and teeth of an ancient rhino.
