An extraordinary fossil goniatite for its quality and size. These images speak volumes, a delightful specimen.The sediments of time have created distinctive linear calcite definition of the inner shell morphology, this form in the fossil bedding plane through a process of permineralisation, this is a cell by cell transformation of the once living tissue.
Once collected the goniatite has been patiently worked out of the fossil bed, limestone stripped away from the fossil to reveal the inner ceratitic chambers. A unique occurrence which has is highlighted through the fossil preparation process.
a distant relative of nautili, octopi and modern squids, an ammonoid which is also a mollusc, this is the result of 400 million years of deposition and fossilisation, which has preserved the outer shell of the mollusc. The goniatite once had tentacles like a cuttlefish which it would use to grapple prey to force down into its mouth and eat with a horned beak-like structure in its mouth much like a modern-day squid.
