Chondrichthyes: Fossil Record. Sharks and their kin are sometimes described as "living fossils," and they are indeed part of an ancient clade of Fossil Chondrichthyes from the Lower Barton and Bracklesham groups of the Hampshire basin book. Very recently, fossil denticles (scale-like bony pieces embedded in or on the skin) that resemble chondrichthyan scales in minute detail have been found in the Late Ordovician of Colorado (Sansom et al.

The fossils are common Bracklesham species, probably from the Selsey Formation, at no great depth, stratigraphically below the Barton Clay. In the Hampshire basin, at Bracklesham and other places, the lithological character of these strata is very inconstant, but they consist of the following series of strata, which are partly quite local: Upper Bagshot Sands, &c.

David Bone (UK) “I have been greatly disappointed [owing to] sand, sometimes two to three feet in thickness, or the tide not leaving the shore sufficiently exposed; so that a stranger might conclude that there were no fossils to be procured at Bracklesham”.

The Sussex geologist, Frederick Dixon, writing about Bracklesham in warned. The London Clay of the Hampshire Basin and the higher parts of the succession in the London Basin represent much shallower water conditions than the previous community.

There is great variation in the fossil assemblages from bed to bed and this probably represents a mosaic of bottom communities which developed in a shallow shelf sea 20—50m deep. Among the shells, the Cardita planicosta, before mentioned (fig.

p. ), is in abundance ; and this fossil and some others identical with European species, or very nearly allied to them, make it highly probable that the Claiborne beds agree in age with the central or Bracklesham group of England, and with the calcaire grossier of Paris.*.

Probably equi- valent to unit $4. Other units have at times been exposed, but their position in the succession 6. MINOR STRUCTURES Bracklesham Bay and the Selsey Peninsula are situated on the northern limb of the Hampshire Basin syncline, and the Tertiary beds have an overall regional east-west strike across the area (Wrigley & Davis, ).

All lie within the Hampshire Basin of southern England. This coastal stretch is famous for its extensive range of well-preserved Eocene fossils found in the sea cliffs and on the foreshore.

The most fossiliferous area is sometimes referred to simply as ‘Barton’, and the clays and sands in which the fossils are found as the ‘Barton Beds’.

Charcharodon megalodon shark's tooth ( inches) from the Bone Valley phosphate beds in Central Florida, Middle Eocene to Lower Pliocene. Charcharodon megalodon is believed by some scientists to have been the largest predator to ever exist on earth ranging up to feet in length.

A revised correlation of the upper Selsey division and lower Barton Clay Formation of the Hampshire Basin is given. A large and previously unnoticed hiatus is shown to be present between these strata at most localities. Bracklesham Group, fossils not only from Bracklesham Bay and the Selsey Peninsula but also from Lee-on-the-Solent and from.

INTRODUCTION. Mobulids represent the largest extant rays inhabiting subtropical and tropical waters worldwide. Like other members of the Myliobatiformes, the 11 living mobulid species (belonging to the genera Mobula and Manta) have broad, well-developed pectoral fins and in certain species, a caudal spine and a whip-like other Myliobatiformes, mobulids are filter feeders (preying.

Chondrichthyes Fossils: Megalodon, Sharks, Rays & kin The Chondrichthyes (meaning “cartilage fishes” for their completely cartilaginous skeletons) are comprised of the Holocephalans (chimaeras), the Batoids (rays, including skates and sawfish), and the group of fish that are perhaps the most intriguing to all humans: the Selachians (sharks).

They provide a near-continuous succession through the Thames, Bracklesham and Barton groups (Lower and Middle Eocene): UK Grid Reference SZ During the Eocene, the Hampshire Basin was located at the seaward end of an easterly draining estuarine complex (Plint,Plint,Plint,Edwards and Freshney,Jones.

The Bracklesham Beds lie between the Barton Clay above and the Bournemouth Beds, Lower Bagshot, below. In the London Basin these beds are represented only by thin sandy clays In the Middle Bagshot group. In the Paris Basin the “Calcaire grossier” lies upon the same geological horizon.

Fossils of the bowfin Amia (Fig. 16) are recorded from the Green River shales at Fossil Butte and in stream deposits from Cretaceous to Recent.

This fish is still another "living fossil." Amia is a nocturnal predator. Presumably, the Eocene Amia had similar habits. The body in Amia has become elongate, as has the dorsal fin. The thickness of the scales has been reduced, but they are still.
