This listing is for one tooth fossil. This image is a representation of what you can expect to receive. You may not receive these exact specimens, but similar. Most teeth are around ¾ – 1¼" wide and serrated. All specimens are ethically sourced.
Squalicorax, commonly known as the crow shark, is a genus of extinct lamniform shark known to have lived during the Cretaceous period.
These sharks are of medium size, up to 5 m (usually around 2 m) in length. Their bodies were similar to the modern gray reef sharks, but the shape of the teeth is strikingly similar to that of a tiger shark. The teeth are numerous, relatively small, with a curved crown and serrated, up to 2.5 – 3 cm in height (the only representative of the Mesozoic Lamniformes with serrated teeth). Large numbers of fossil teeth have been found in Europe, North Africa, and North America.
Squalicorax was a coastal predator, but also scavenged as evidenced by a Squalicorax tooth found embedded in the metatarsal (foot) bone of a terrestrial hadrosaurid dinosaur that most likely died on land and ended up in the water. Other food sources included turtles, mosasaurs, ichthyodectes, and other bony fishes and sea creatures. Tooth marks from this shark have also been found on the bones of Pteranodon, but whether the shark actively snatched such large pterosaurs out of the air, attacked them as they dove after prey, or was simply scavenging is not known.
I love curiosities of all kinds but shark teeth have always been my favorite finds and this is the first tooth I purchased and I love it. It’s so cute and chubby
