ABOUT THE SPECIMEN:

This well-preserved Terebratulid brachiopod hails from the iconic marine Inferior Oolite Group of Dorset, UK. Characterised by clear growth lines, a smooth biconvex shell, and a defined pedicle foramen, these fossils offer excellent morphological detail.

Collected from Bajocian-aged beds laid down in a warm, shallow marine shelf, these brachiopods thrived in oxygenated, lime-rich conditions during a time of intense marine diversification. Their presence is a hallmark of the carbonate ramp system of southern England during the Jurassic.

PALEONTOLOGICAL FEATURES:

• Morphology: Typically biconvex shell with a short hinge line, small to moderate pedicle opening, and smooth or finely costate surface depending on exact genus. Shell is compact and tear-drop shaped, typical of Terebratulida.
• Preservation: This specimen retains fine external shell detail with visible muscle scars in some examples. Colour and mineral replacement consistent with classic Inferior Oolite preservation.
• Depositional Environment: Open marine, low-energy carbonate platform with periodic storm influence. Sediment mostly oolitic limestone and bioclastic grainstone.
• Significance: Terebratulid brachiopods are an essential component of Jurassic invertebrate faunas and are useful for environmental reconstructions and stratigraphic correlation. They are often used to assess palaeoecological conditions in Bajocian seas.
• Collector’s Note: These brachiopods are commonly used as type specimens in classic palaeontological works on the British Jurassic. Many species within the group were described as early as the 19th century by palaeontologists such as S.S. Buckman and J. Morris.
