Otodus Obliquus Shark Teeth Fossil Block 360mm


Availability:In stock


A fossil find of a very rare occurrence of an Otodus Obliquus Shark Tooth block containing twelve good examples and one centrum vertebrae of the same individual prehistoric Mackerel shark which attained sizes of between 30ft to 40ft (9m to 12m), in length and attaining something around 3 to 5 tonnes in weight. This weight is an estimate based on the modern-day Gt. White shark's, up to 25ft and weighing around 6600 lbs or 3 tonnes. Another interesting shark statistic, the Gt. white tooth is an average of 1.5ins to 2ins for an adult shark of around 20ft to 25ft. The prehistoric fossil record shows Otodus obliquus Mackerel shark teeth, attained sizes up to 4ins. Read the fuller description below...

Otodus Obliquus Shark Tooth block containing Mackerel shark teeth along with one centrum vertebrae, there may well be more teeth encapsulated within the rock block, the block being a solid phosphate rock which was once the late palaeocene seabed. The Mackerel sharks were the apex predator of the time and from this lineage, the modern Great White Shark developed.


Did you know the teeth of the Otodus genus were named from the Greek, the meaning Otodus derives from the ear-shaped tooth. The Otodus sharks ranged worldwide, fossil teeth have been found in the fossil record across many continents.


The condition of the teeth is excellent, displaying a very pleasing light French beige colour tone to the dentin-enamel which has very good preservation. the block has had conservation inasmuch as the overburden of rock has been removed from the teeth. The matrix block is crammed with other interest, some of which appear to be shark vertebrae elements.


The Otodus obliquus was a very large Macro-predatory shark with the largest recorded tooth measuring 10.4 cm in length. With each discovery, we are able to determine more about these powerful sharks which roamed the prehistoric seas of the Cenozoic era. Otodus was a fearsome predatory shark growing to a maximum length of 39 feet. Their prey being smaller marine mammals including smaller sharks. Scientist and palaeontologists theorise the Otodus obliquus ancestry connects to that of the great Megalodon from the Miocene era, evolving for around 30,000,000 to 40,000,000 years and now down we can enjoy the modern Great white sharks. This is the lineage of Carcharocles as we understand it today.
