Heteromorph ammonites are highly collected throughout the world due to their bizarre shapes. This particular specimen is a large section of one of these uncoiled ammonites. The section has been beautifully preserved and has strong ribbing throughout. A large and highly collectable section.
A really nice example of a Promicroceras ammonite overlying a piece of fossilized driftwood from the ancient "Monkey Puzzle" tree. The matrix has a cut base for upright display. The solid calcite ammonite has been predated on and a chunk taken out of it which almost certainly caussed its death, either by a Dapedium or Furo, two predatory fish around at this time. Approximately 200 million years old.
Thee highly irridescent ammonites are amongst the prettiest fossils you can find in the British Isles. This example shows wonderful flashes of lilacs, greens, yellows, reds and purples when held at different angles to the light. These are not just beautiful fossils for the collector but could be used in jewellery in a dramatic way.
This is quite a superb matrix free example which has been preserved to the centre on both sides. The specimen is very dark and has occasional flashes of colour when held at different angles to the light. This is a superb specimen, one for the collector.
