Crinoid fossils. Rock containing crinoid (or sea lily) fossils. These are Scyphocrinus elegans crinoids from the Silurian/Devonian period (about 440-360 million years ago). Crinoids are marine echinoderms that appear as early as the Ordovician period (500 million years ago). These crinoids have stalks by which they would attach themselves to the seabed, capturing food with feathery arms that formed a cup (seen at lower right and upper centre). Thousands of extinct crinoid species have been…

I like really old shells too - like 40 or 50 millions years old. I have several nice amonites. -CAB

Sinosauropteryx: The first genus of dinosaur outside of Avialae (birds and their immediate relatives) to be found with evidence of feathers. Which can be seen clearly in this gorgeous fossil.

An armoured jawless fish (a Cephalaspis, which is a kind of osteostracan). This creature evolved as it adapted to the transition from open sea to freshwater conditions in the Ludlow area towards the end of the Silurian. It had not evolved at the time the rocks beneath Whitcliffe were laid down, but fossils of the animal have been found in the younger rocks just to the east, downstream of Ludford Bridge.

Fossilised spider 'biggest on record'  The female, which lived about 165 million years ago, belongs to a collection of spiders well known today - the golden orb weavers.  Until this new fossil turned up in Inner Mongolia, the most ancient example from this grouping, or genus, was about 35 million years old.
