Plesiosaur Tooth - Classic Riker Box Specimens
Plesiosaur Tooth - Classic Riker Box Specimens
Limited Availability: These teeth are top grade and very difficult to find. If we run out, please sign up for email notifications and we'll let you know when more arrive.
Featuring a long, snake-like neck and a stout body equipped with slender paddles, Plesiosaurs are one of the most readily identifiable of all ancient marine reptiles.
This specimen is a Plesiosaur tooth recovered from deposits in Morocco and dates to the late Cretaceous Period.
Classic Riker Box Specimens
Three sizes are available:
Medium: 1-1.5" (~2-3cm)
Large: 1.5-2" (~3-5cm)
Extra-Large (XL): +2" (~5cm+)
Each specimen comes inside a classic, glass-topped riker display case. The Medium and Large case measures 4 1/2" x 3 1/2" and the Extra-Large (XL) case measures 5"x6". A small information card is also enclosed that also serves as the certificate of authenticity.
Individual Showcase Specimens
Plesiosaur in Matrix
We're excited to announce the addition of Plesiosaur teeth in matrix to the collection. Click here to browse our entire selection of available teeth.
We have limited numbers of matrix teeth and they are sold and priced individually based on the size and the additional inclusions. Matrix teeth ship in our heavy cartons and are carefully packed with extra cushioning. As with our riker box specimens, the matrix teeth also include a small information card that serves as the certificate of authenticity.
📸 Examples of Plesiosaur Tooth specimens along with varieties in matrix. Matrix teeth with inclusions like this are rare.
Please Note: All teeth will show signs of repair (typically small cracks repaired with penetrative stabilizers). Some teeth will be reassembled. This is the nature of this item and is completely normal.
In addition, to protect the specimen during transit every Plesiosaur tooth is individually wrapped. On receipt, simply open the top of the case and unwrap the tooth and then arrange the tooth inside the case as pictured here on the site. We also recommend placing the bubble wrap under the soft, white lining of the case. This extra padding will keep the tooth snug in the case after the lid is secured.

MORE ABOUT PLESIOSAURS
"Like a sea serpent run through a turtle." ~ William Buckland, Oxford University Geology Lectures, 1832
Featuring a long, snake-like neck and a stout body equipped with slender paddles, Plesiosaurs are one of the most readily identifiable of all ancient marine reptiles. Biomechanical reconstructions suggest that Plesiosaurs moved through the water in the same way that turtles or penguins do, more like flying than swimming. Scientists have also discovered that Plesiosaurs used their unique bodies to hunt for bottom-dwelling crustaceans.
With nearly 140 million years in the fossil record, Plesiosaurs were incredibly successful creatures. As air-breathing reptiles, they lived near the surface in the open seas, and were able to spread around the world. Fossilized skeletons of Plesiosaurs have been found in Europe, North America, and Australia. New paleontological evidence suggests that Plesiosaurs may have given birth to live young instead of laying eggs, adding an interesting twist to a very unique family of reptiles.

PIONEERS IN PALEONTOLOGY
MARY ANNING (1799-1847)
The story of marine reptiles such as the Plesiosaur, not to mention our modern understanding of species extinction, would be incomplete without discussing the contribution of Mary Anning (1799-1847).
Ms. Anning was born to a working-class family in Lyme Regis, a small town on the Dorset coast of southern England. Like many in the area, Anning's family sold fossils recovered from the cliffs, but for Mary, it would become a primary source of revenue, and later a connection to the much wider world of science.
Her most notable finds include the first complete Ichthyosaurus and the first two complete Plesiosaurs (the first of which is also credited to her brother Joseph). She is also credited with being the first to recognize the importance of coprolites and had extensive knowledge of ammonites.
Above: Portrait of Mary Anning by an unknown artist, sometimes referred to as Mr. Grey. In the background is the Golden Cap headland, the highest point on the South Coast of England. Sleeping in the foreground is Tray, Ms. Anning's dog and fossil collecting companion. Tray was trained to sit next to interesting finds while Anning retrieved her equipment from other locations. He perished under a sudden cliff-face collapse in 1833 which nearly took Ms. Anning's life as well.
Yet, despite her firsthand experience and deep knowledge of these subjects, Ms. Anning was unable to take part officially in the scientific societies of the day which were only open to men. Her discoveries and observations were instead shared through others, with the one notable exception being her drawing of a complete Plesiosaur. In this instance, the noted French anatomist Georges Cuvier proclaimed the animal a hoax. It would take numerous examinations and debate before Cuvier would reverse his position and admit he'd rushed to judgement.
Ms. Anning died in 1847 of breast cancer. It would take another 163 years for the Royal Society to recognize her influence in the advancement of science.
