Ammonite fossil, SEM
Ammonite fossil, coloured scanning electron micrograph (SEM). Ammonites were invertebrates and lived in the sea. They were molluscs that formed a spiral shell to protect their soft body. The lines on the shell mark chambers added as the ammonite grew. It lived in the newest and largest chamber. Shells ranged in width from under 1 centimetre to over 1 metre. Ammonites most closely resemble the present-day nautilus. They first appear in the fossil record around 400 million years ago and became extinct at the end of the Cretaceous period 65 million years ago. Magnification: x30 when printed 10cm wide

EDITORS COMMENTS
This print showcases the intricate beauty of an Ammonite fossil, captured through a coloured scanning electron micrograph (SEM). These ancient creatures were invertebrates that once thrived in the depths of the sea. To protect their soft bodies, they developed a remarkable spiral shell, which is clearly visible in this image. The lines etched on the shell serve as markers for chambers that were added as the ammonite grew. It resided within its newest and largest chamber. The size range of these shells was truly awe-inspiring, spanning from under 1 centimetre to over 1 metre in width. Ammonites bear a striking resemblance to their present-day relative, the nautilus. Their existence can be traced back approximately 400 million years ago when they first appeared in the fossil record. Unfortunately, these magnificent creatures met their demise at the end of the Cretaceous period around 65 million years ago. Through magnification at x30 when printed at just 10cm wide, this SEM image allows us to appreciate every minute detail preserved within this fossilized marvel. This photograph not only provides insight into Earth's ancient past but also serves as a testament to nature's extraordinary ability to create such diverse and fascinating life forms throughout history.
