F001 A pentasrinates crinoid plaque (UK)

Crinoids have graced the oceans for more than 500 millions years. Amongst the most attractive fossils, they played a key role in the ecology of marine invertebrates called echicoderms, which include starfish, sand-dollars, sea-urchins and sea cucumbers.

F003 A superb ammonite fossil (Madagascar)

This is a large example of this species. Rarely do these ammonites show such an excellent display of colour, seen here in red iridescence.

Weight: 3.5KG Width: 21cm

F004 A stunning Craspedodiscus sp. ammonite fossil

(Saratov region, Volga river formation, Russia)

Jurassic (208-146 million years old)

Weight: 6.7KG Width: 35cm

F005 An extremely rare red Dakotan "coupling" Splenodiscus sp. ammonite with host rock showing some ammonite shell material and fitting neatly

(South Dakota, USA) Cretaceous (110-65 million years old)

A truly remarkable example due to its high red iridescence and natural detachability from the host rock. A museum grade example.

Weight: 19.3KG Width: 31cm

F006 A fine polished Lytoceras sp. Ammonite (Madagascar)

A superb example of this distinctive species, part of the original mother-of-pearl shell has been revealed showing as a rare vivid green shimmer on one side of the specimen.

Weight: 16KG Width: 30.5cm

F007 A Large Polished Ammonite (Madagascar)

Jurassic period (208-146 million years ago)

The polishing process has revealed the intricate Suture lines of this species in striking detail. The Darker colouration in the ammonite is due to the Presence of pyrite in the sediment that has filled the chambers during fossilisation.

Width: 26.5cm

F008 A fine English Liperoceras sp. ammonite fossil (Lyme Regis, Dorset, UK)

(208-146 million years ago)

A more unusual species of ammonite from this locality in an excellent state of preservation.

Weight: 1.5KG Width: 15cm

F009 A fine and rare Aegasteroceras Sagitttarium ("Scunny" ammonite) fossil (Obtusum Zone, Frodingham Isonstone, Scunthorpe, England)

(208-146 million years ago)

A classic example of this rare English ammonite on its original matrix. The localities producing this species are no longer accessible, making this a highly sought-after fossil.

Weight: 10KG Width: 30cm

F010 Extremely rare-one-of-a-kind Kranospinctes showing red and green polished shell (Madagascar)

(208-146 million years ago)

An excellent example of the species which unusually stands unaided on the nodules of its shell.

Weight: 28.5KG Width: 43cm

F011 An extremely rare Lepidotus fossil fish-head

(Saltwick, near Whitby, Yorkshire, UK)

(192-146 million years old)

Examples of this species almost never appear on the market for sale. The outcrop which produced this fossil no longer exists so most specimens only occur in private collections or museums. However it is the extraordinary state of three-dimensional preservation which is most notable on the specimen here offered. The fish was not flattened during fossilisation but retained its volume and original shape, with much of the skeletal detail still clearly visible.

Weight: 5KG Width: 32cm

F012 Megladon tooth (USA)

(5-10 million years old)

The giant shark-like Megladon, growing to an estimated 16m length, is one of the most celebrated and controversial prehistoric fish. Ancient sharks, like their modern counterparts, have skeletons composed of cartilage, which is prone to swift decay. Most knowledge of the Megladon has been gleaned from its teeth, broadly similar in shape and in the serrated edges to those of the modern Great White Shark. The current consensus is that the Megladon belongs to the similar but separate genus of Carachocles.

Height: 13cm

F013 A partially pyritised Speetoniceras split Ammonite (Russia)

(208-146 million years old)

A stunning example from this famous locality. The presence of large amounts of iron during fossilisation results in these highly pyritised ammonites, a striking combination of black and gold.

Weight: 5KG Height: 26cm

F014 An attractive pair of ammonites (Madagascar)

(208-146 million years old)

This ammonite has been cut in half to reveal the internal structure of the shell. In life, the last chamber was occupied by the animal itself, which resembled a modern-day squid. Calcite and darker aragonite crystallisation are shown here in this specimen, which are sometimes called "caramels" because of the gorgeous brandy colouration.

Weight: 2.2KG Width: 19cm

F015 Lytoceras fimbriatum (ammonite) specimen

(Dorset, England)

(198-193 million years old)

This specimen is showing fine external shell and internal suture detail.

Weight: 6KG Width: 26cm

F016 A polished Cenoceras sp. or Nautilus specimen (Madagascar)

(180-185 million years old)

Nautili are living fossils that have been around for over 300 million years. The present example has been polished to reveal the beautiful iridescent shell.

Weight: 3KG Width: 18cm

F017 Dakota Ammonite (USA)

 This is an example of the ammonite Hoploscaphites nicolletti of the Fox Hills Formation deposits of South Dakota. During the Cretaceous, much of the Western United States was covered by what is termed the Western Interior Seaway, a broad shallow (100-300 m maximum depth) sea that was home to various aquatic reptiles, fish, and ammonites. Ammonites of this degree of preservation are difficult to come across. The high degree of preservation of its natural mother-of-pearl shell makes it appear to be preserved as opal. This is a consequence of light passing through the various layers of aragonite and conchiolin deposited by the ammonite in life. Notice how the colors change with changing perspective.

Weight: 3KG Height: 26cm

F018 A fine pair of agatised fossil corals (USA)

(23-5 million years old)

Florida agatised coral is famous for its beauty and uniqueness. It is found all over Florida in many forms and colours. Sometimes it is solid but those from location such as Tampa Bay are hollow and can be called geodes. Scientifically it is identified as a chalcedony pseudomorph after coral because one mineral, the coral, has been replaced by another quartz.

Weight: 1.9KG Width: 16cm

Weight: 8KG Width: 22.5cm

F023 A good keichousaurus hui fossil

 in  a dark solid walnut frame (China)

(245-208 million years old)

The keichousaurus, a small, early reptile growing up to a circa 30cm in length, represents the amphibious transition between land-dwelling and fully marine reptiles; they could swim easily, using the tail for propulsion and the legs for paddles, but the size of the bones in the limbs and apparent strength of the hips and shoulders suggest that they were equally at home walking on land.

Visible Matrix: Width: 18cm Height: 23.2cm

F024 A good keichousaurus hui fossil

 in a dark solid walnut frame (China)

(245-208 million years old)

This marine reptile lived about 220 million years ago, and was probably ancestor to other marine reptiles such as the plesiosaur, which became extinct with the dinosaurs.

Visible Matrix: Width: 16.2cm Height: 23.1cm

F025 An excellent mesosaurus Brasiliensis fossil in a dark solid walnut frame (Brazil)

(286-246 million years old)

Mesosaurus were fast swimming fresh water predators and were the first reptile to return to the water and become fully aquatic, developing long broad tails and long hindlegs for power and steering. An excellent example in a life-like pose.
