Interesting Flint Facts: Chalk cliffs are an excellent place for flint. When the chalk weathers away, flint nodules fall off. When flint is struck against steel or two flintstones are struck together, they can produce a spark.
For centuries, this was a way for people worldwide to made fire. People carried a small box called a tinder box which had some flintstones and cloth, bark or sawdust. The hard flint edge shaves off a particle of steel that exposes iron which reacts with oxygen and can then ignite tinder. Flints were also used to make a spark to fire a gun. This type of gun was called a flintlock gun and was introduced in the 17th century and continued to be popular for two centuries.
They were used as a self-defense weapon and as a military arm. The firearm had a metal plate that produced a spark when struck with chert. A wide range of fossils can be found within flint nodules, indeed in many instances the nodule itself is in fact an internal mould of a sea creature. The silica accreted around the nuclei of organic remains and biogenic structures, such as the remains of sponges or the burrows of crustaceans.
Therefore the flint fossils you find reflect the diversity of life and the activities of creatures on the seafloor at that time. Among the most commonly found flint fossils include sponges, echinoids, shells and of course trace fossils i. Pseudo flint fossils Flints nodules are often mistaken for fossils.
Since Discovering Fossils was launched we've received countless emails from visitors claiming to have discovered a variety fossilised objects. Among the best includes a 'fossilised human foot', a 'man's arm' and a 'goat trotter'! None of these were in fact fossils strictly speaking, instead what they had discovered were flint nodules that had formed to resemble such objects pseudo fossils. However it is likely that these objects were trace fossils, such as lobster burrows.
In these instances the silica would have filled and overgrown the creature's burrow, thus forming a flint copy of the structure. Join us on a fossil hunt Left: A birthday party with a twist - fossil hunting at Peacehaven.
Discovering Fossils guided fossil hunts reveal evidence of life that existed millions of years ago. Whether it's your first time fossil hunting or you're looking to expand your subject knowledge, our fossil hunts provide an enjoyable and educational experience for all.
