Name: Machaeracanthus sp. (Spiny Shark)
Specimen: Shark/Fish
Age: Devonian ~ 417-354 million year old
Location Found: Alnif, Morocco

The Machaeracanthus fish lived during the Devonian period and is a prehistoric type of fish that resembles both shark and bony fish. These fish are also known by the name “Spiny Sharks” (Acanthodii), which was given to them due to their shark-shape – a streamlined body, paired fins, and a strongly upturned tail. They also had large immovable bony spines formed of dentine supporting all the fins, except the tail – hence, “Spiny Sharks”. The body was covered in small mosaic-like scales and they possessed small teeth which were typically confined to the lower jaw, though some were toothless. Fossilized spines and scales are often all that remains of these fish in ancient sedimentary rocks.

ACTUAL AS SEENThe image shows the EXACT unique specimen you will receive. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device.
