The Charmouth Mudstone Formation is a geological formation in England, dating to the Early Jurassic (Sinemurian–Pliensbachian).[1] It forms part of the lower Lias Group. It is most prominently exposed at its type locality in cliff section between Lyme Regis and Charmouth (alongside the underlying Blue Lias) but onshore it extends northwards to Market Weighton, Yorkshire, and in the subsurface of the East Midlands Shelf and Wessex Basin. The formation is notable for its fossils, including those of ammonites and marine reptiles and rare dinosaur remains. The formation played a prominent role in the history of early paleontology, with its Lyme Regis-Charmouth exposure being frequented by fossil collectors including Mary Anning.

Stratigraphy

Shales With Beef Member

The Shales With Beef Member is around 28–30 metres thick in the Lyme Regis-Charmouth region and predominantly consists of thinly bedded medium to dark grey mudstone, blocky calcareous pale-weathering mudstone and brown-grey organic-rich mudstones with frequent bedding parallel veins of fibrous calcite ("beef"), that are usually less than 10 centimetres thick. Several beds of nodular and tabular limestone are also present. It is the lowest unit of the formation and directly overlies the Blue Lias Formation, with the boundary being marked by a prominent bioturbated horizon. Notable persistent marker beds within the member include the laminated calcareous siltstone "Fish Bed", "Table Ledge", which consists of lens beds of limestones with mud content with nests of rhynchonellid brachiopods, the Devonshire Head and the Spittles limestones and the Birchi Nodules (which are septarian concretions) The upper boundary with the Black Ven Marl Member is marked by the prominent laterally persistent limestone Birchi Tabular Bed.[2]

Black Ven Marl Member

The Black Ven Marl Member is around 43 metres thick consists of thinly bedded dark mudstones,[3] with several laterally persistent cementstone horizons, notable horizons include the Lower and Upper Cement beds and the Stellare nodules.

Belemnite Marl Member

The Belemnite Marl Member is around 20 to 27 metres thick, and consists of interbedded pale and dark grey calcareous mudstone, with numerous belemnites, hence the name. The top of the member is marked by the Belemnite Stone Bed[4]

Green Ammonite Member

The Green Ammonite Member is up to 31 metres thick predominantly consists of medium grey mudstones, with 3 limestone horizons, Lower Limestone; Red Band, and Upper Limestone, it is conformably overlain by the Dyrham Formation in some areas,[5] but in the Charmouth area there is an erosive unconformable boundary with the much younger Early Cretaceous (Albian) aged Gault clays.

Lower Pliensbachian member

Associated remains of the rostrum and mandibles

A basal dimorphodontid pterosaur. The relatively deep rostrum and extreme size dimorphism in the dentition show clear similarities to Dimorphodon, also from the Lias of Dorset. The distinctive dentition, in which the first four pairs of rostral teeth and two pairs of mandibular teeth are relatively large and fang-like, while the remaining teeth are remarkably small and short.[21]

Dinosauria

Genus Species Location Stratigraphic position Material Notes Images

Coelophysidae[22][23]

"Megalosaurus" lydekkeri

Lyme Regis

Black Ven Marl Member

  • NHMUK OR 41352, isolated tooth

A theropod, possibly a member of Coelophysidae inside Neotheropoda. Invalid and non diagnostic. It was identified as Zanclodon(?) sp. b., Megalosaurus lydekkeri and reassigned as Magnosaurus(?) lydekkeri.[24] Mortimer found that was changed to "Megalosaurus" woodwardi later.[24] It was found on mostly of recent works to be non diagnostic, probably a coelophysoid.[23]

Dornraptor[25]

D. normani

Lower cliff face, Charmouth

Black Ven Marl Member (Likely)

  • NHMUK OR 39496, Partial hind limb
  • GSM 109560, left femur

An Averostran theropod, possible Ceratosaur or Tetanuran. In 2024 was formally described, but referred to the older Blue Lias.[25] A paper non quoted on the description relocated it on the Charmouth mudstone.[26]

Neotheropoda[26]

Indeterminate

Near Lyme Regis

obtusum Zone, obtusum subzone

  • NHMUK PV R36855, Left fibula, ~ 17 cm long

A theropod, possibly a basal member of Neotheropoda. Previously misidentified as a referred specimen of the pterosaur Dimorphodon macronyx.[27] NHMUK PV R36855 differs from those of all other Early Jurassic-Late Triassic, theropods in its combination of features, but bears no discernible autapomorphies.[26] It is similar to Tawa, Dracoraptor and Liliensternus, being considered an early branching neotheropod, with a size range similar to Coelophysis bauri, representing an individual of approximately 10 kg, approximately the same size as Coelophysis bauri.[26]

Massopoda[28]

Indeterminate

lower cliff face, Charmouth

obtusum Zone, obtusum subzone

  • GSM 109561 pedal ungual

A sauropodomorph, possibly a member of Massopoda. While it was not associated with BMNH 39496 or GSM 109560 and was not assigned to "Merosaurus" it was classified as coming from an indeterminate theropod. Mortimer found closer resemblance with pedal unguals of basal massopods like Blikanasaurus and Jingshanosaurus.[29]
