Neuropteris gigantea is a fern from the Carboniferous Coal Measures of Westphalian age.  This frond tip has been photographed wet and dry in order to assess the best way of showing the veins on the pinnules.  The specimen is from the underground seams of the Nottinghamshire Coal Measures.


Astroceras obtusum

This 18 cm ammonite is a deferred specimen of Astroceras.  It was found in glacial till and must have been eroded from the Jurassic Rocks of the UK during the Devensian Ice Age to be deposited in South Lincolnshire.  The specimen is very complete, but shows a lot of surface damage.

The shell is largely intact, but where it has been shattered during glacial transit, the thickness of shell and the underlying chamber sutures are clearly visible.  The suture pattern is not seen on the surface of the shell.

In parts, where the shell has been completely removed, the chambers are exposed.  They show crystal filled cavities and it is clear that if this specimen was sectioned, it would be quite spectacular.  However, without provenance of its origin, the specimen has little scientific value.  It is a good door stop.


These three seeds are from a Pleistocene deposit at Maxey near Peterborough, UK.  Many seeds are preserved in sediments and they are a good ecological indicator of the environment type.  These types of seed do not travel very far, so if they are found in significant numbers, it is likely that the environment, in this case, was mixed woodland.  Many fossil collectors miss important clues such as these when they are on a quest to find big and bold fossils.  It takes a scientific mind to look at the whole picture.


Dalmanites Myops is one of the Dudley Bugs from the Silurian rocks of the West Midlands, UK.  It was a bottom dwelling species with a well-developed compound eye.  This species would have been able to see the approach of predators and have the ability to bury itself in the muddy sea floor.

Pliosaur Tooth

Pliosaurs are large marine reptiles from the Mesozoic seas.  They generally have stubby teeth with hollow bases and rounded tops.  The length and diameter of the tooth will vary depending upon its position in the jaw.  At the back of the jaw, the teeth will be very short and may be as wide as they are tall.  At the front of the jaw, the teeth will be much longer and appear more pointed.  This tooth is typical of those found in the middle of the jaw.  These are strong teeth associated with large jaws that have a very muscular and powerful bite.

Brachymetopus pygidia

Brachymetopus ornatus is a small trilobite from the Carboniferous Limestone of Derbyshire, UK.  It is Dinantian in age.  This specimen shows the pygidia of different fossils from the area of Treak Cliff Cavern near Castleton.  The pleura show raised spheres of carapace along their segments.

This small trilobita is preserved in a reflexed state.  The cephalon is bent under the pleura and in this specimen the margines of the fossil are eroded.  The image seen here has been taken from the top and bottom to show the whole specimen, the underlying areas have been photoshopped out in each view to give a clearer image of the amount and state of preservation.  The specimen, Kaskia chesterensis, is from the Carboniferous.
