From an old collection, this specimen has been left untouched as any preparation would ruin the patina that has been built up over the years. The specimen has two bivalves attached, one in the mouth border and the other near the centre of the ammonite. The ammonite exhibits the sutures which are so characteristic of this well known and popular Upper Lias ammonite.
A very rare ammonite from the Oolite which has been preserved in calcite. The ammonite itself lies in the centre of a thin piece of matrix. It was discovered during a temporary exposure in 2009. A very good aquisition for the collector. Approximately 170 million years old.
A fantastic and rare example to see an Arnioceras with a clear bite taken out of it, either by a Dapedium or Furo, two predatory fish around at this time. A very interesting study fossil. Approximately 200 million years old.
This fossil exhibits two solid calcite ammnites in a highly aesthetic position. Each one has an immaculate centre. The matrix surrounding the ammonites has a cut base for upright display. Approximately 200 million years old.
