EDITORS COMMENTS
This stunning print captures the intricate details of a Tonguestone, also known as a shark's tooth, with lateral denticles. The specimen originates from the London Clay in Sheppey, Kent, dating back to the Eocene period. This extinct shark species, Lamna obliqua Agassiz, belonged to the Lamnidae family and is a fascinating example of ancient marine life.
The image showcases not only the sharp and pointed main tooth but also the smaller lateral denticles along its edges. These denticles served as additional cutting surfaces for this predatory fish, highlighting its impressive anatomy and adaptation for hunting prey.
Found in Europe, particularly Great Britain, this fossilized tooth provides valuable insights into the evolution of chondrichthyes or cartilaginous fishes like sharks. The detailed preservation of this specimen offers a glimpse into prehistoric marine ecosystems and adds to our understanding of these enigmatic creatures.
As we marvel at this piece of natural history frozen in time, we are reminded of the rich biodiversity that once thrived in our oceans millions of years ago. This print serves as a testament to the enduring legacy of these ancient animals and their significance in both scientific study and folklore.
