This is the second Coin Collection from the Royal Mint UK's stable that features prehistoric creatures and is titled “Tales of the Earth.” 

The Royal Mint, in collaboration with the Natural History Museum, has released on 25.02.2021 a new commemorative coin collection celebrating fossil hunter and pioneering palaeontologist Mary Anning (1799–1847), who is regarded as one of Britain’s greatest fossil hunters.

About Mary Anning:

Mary Anning was born in 1799 in the town of Lyme Regis, Dorset — which is now referred to as the “Jurassic Coast,” and spent her entire life in this small seaside town on England’s south shore. 

Designed in coordination with experts at the Natural History Museum, the augmented reality brings the mighty beasts to life. To access the augmented reality feature, collectors can visit The Royal Mint website to unearth exclusive content. 

The first release in the Mary Anning Collection features Temnodontosaurus

About Temnodontosaurus:

Temnodontosaurus (Greek for “cutting-tooth lizard” - temno, meaning “to cut”, odont meaning “tooth” and sauros meaning “lizard”) is an extinct genus of ichthyosaurs from the Early Jurassic, ranging between 200 and 175 million years ago (Hettangian - Toarcian), and known from Europe (England, France, Germany and Belgium) and Chile. 

They lived in the deeper areas of the open ocean. 

University of Bristol paleontologist Jeremy Martin described the genus Temnodontosaurus as “one of the most ecologically disparate genera of ichthyosaurs”.

Temnodontosaurus was one of the largest ichthyosaurs. 

Estimates of the maximum length of Temnodontosaurus have ranged from 9.00 m (29.50 ft) to 12.00 m (39.0 ft). The largest length estimates rival those of another giant ichthyosaur, Shonisaurus popularis, which was previously considered the largest ichthyosaur.

Temnodontosaurus is known for its incredibly large eyes which, at approximately 20 cm (8.0 inches) in diameter, are believed to be the largest of any known animal. It possessed a tail bend which was characteristic of Jurassic ichthyosaurs  and had many conical teeth filling its jaw that were set in a continuous groove.

The number of valid Temnodontosaurus species has varied over the years. 

Christopher McGowan in 1992 believed there were around thirteen species in the genus Temnodontosaurus. 

Michael Maisch in 2000 listed T. platyodon, T. trigonodon, T. acutirostris, T. nuertingensis and T. eurycephalus as the valid species of Temnodontosaurus.

The first skull and skeleton of T. platyodon found by Joseph and Mary Anning in 1811-12.

The first ichthyosaur skull ever discovered was that of Temnodontosaurus platyodon. The specimen (BMNH 2149) was found in the Lias of Lyme Regis by Joseph Anning in 1811. The rest of the skeleton was recovered in 1812 by his sister, Mary Anning, but has been lost since.

 The ichthyosaur was subsequently described by the anatomist Sir Everard Home, in what was the first scientific description of an ichthyosaur. T. platyodon is the type species of Temnodontosaurus and the most common species.

 The type skull is currently located at the Natural History Museum in London. The specimen was originally named Ichthyosaurus platyodon but then renamed Temnodontosaurus. The genus Temnodontosaurus was named by Richard Lydekker in 1889.

Other coins in the collection were Anning’s discoveries of Plesiosaurus and Dimorphodon
