Bernissartia Dollo, 1881
Pronounced
Burn-ISS-arr-tee-AH

Meaning

From Bernissart (in Belgium)
Classification

Crocodylomorpha
Bernissartiidae Dollo, 1883

Bernissartia sp. indet. Buffetaut and Ford, 1979

Stratigraphy
Wessex Formation
Lifestyle
This crocodile would have had similar habits to modern piscivorous crocodiles
Locality
Between Compton Grange and Hanover Point.

Description of Material

Known only from teeth, Bernissartia teeth are recognisable by their low, blunt, rounded profile, although some have an obtuse but somewhat pointed apex and resemble the posterior teeth of many crocodiles. The rest, which are presumably more posterior, have a completely rounded, semicircular profile. Some of the larger teeth are hemispherical, and in occlusal view their outline is regularly oval. others are more elongated, or are laterally compressed. Some are even kidney-shaped, with a fairly sharp conscriction at the midpoint.
The teeth show a distinct ornamentation of the enamel. On unworn crowns, a longitudinal ridge can be seen, from which fine wrinkles radiate on the sides of the crown. Nearer the base, the enamal becomes more smooth, and only show faint growth rings.
As the tooth wore down, the enamel along the ridge would wear down, producing a shallow, narrow groove cutting into the dentine beneath, and eventually forming a flat wear facet.

It has been suggested that Bernissartia is the same as Hylaeochampsa, but until more is known no comparison can be made.

Lifestyle

Locality
Unknown

Description of Material

Goniopholis is best known from scutes and teeth. The scutes are ornamented with deep pitting, and have an almost "waffle-like" appearance.

Goniopholis can be recognised as it has a slightly brevirostrine skull with the lateral margins of the rostrum festooned both vertically and laterally. There is a notch at the suture between premaxilla and maxilla. There is an undivided external naris positioned near the rostral tip of the snout, and the nasals are excluded from the external naris by the premaxillae and ending slightly caudal to the naris. The orbits are smaller than the supratemporal fenestrae. There is a short lacrimonasal suture, and the ventral surface of the mandible is flat and sculptured at the level of the mandibular symphysis.

Hylaeochampsa Owen, 1874
Pronounced
HIGH-lee-oh-CHAMP-sah

Meaning

From Bernissart (in Belgium)
Classification

Crocodylomorpha
Hylaeochampsidae Williston 1925

Hylaeochampsa vectiana Owen 1874

Stratigraphy
Vectis Formation
Lifestyle
This crocodilian appears to have been a molluscivore, using it's button-like teeth to crush the shells of bivalves such as Unio.
Locality
Unknown

Description of Material

A eusuchian possessing the unique derived features of an extensive ectopterygoid bordering extremely broad posterior maxillary teeth and contacting the palatine anteriorly, a flat surface on the occipital faces of the quadrate and pterygoid, an unusually prominent process on the occipital surface of the paroccipital process medial to the cranioquadrate passage, a vertical posterior wall to the supratemporal fossa, a relatively long skull table with a narrow, elongate supratemporal fenestra, a posterior process of the jugal that is twisted dorsomedially around its longitudinal axis, a short distal portion of the quadrate, and an extremely broad prefrontal pillar. Uniquely possesses the combination of a preorbital constriction, enlarged posterior maxillary teeth, and an apparently short rostrum. Derived characters shared with some Eusuchia (but not necessarily synapomorphic)-prominent boss on ventral surface of quadrate (also in primitive alligatorids), lower temporal bar strongly arched dorsally, posterior ectopterygoid process absent (also in some crocodylids), and palatines very narrow between suborbital fenestrae (also in crocodylids).

It has been suggested that Bernissartia is the same as Hylaeochampsa, but until more is known no comparison can be made.

Suchosaurus Owen, 1841

This genus has been removed due to the type material (teeth) being reassigned to the spinosauroidea, and may be synonymous with Baryonyx. However, until anything is published, it's uncertain if the Isle of Wight Suchosaurus is the same or just indet. crocodilian material lumped within the genus

Description of Material

Piscivorous mesosuchian crocodilian of small size. Slender, moderately elongate snout sharply demarcated from the posterior part of the skull. Nasal bones reaching premaxillae. Orbits large and rounded, facing forwards and sidewards. Supratemporal openings about as large as the orbits. Postorbital pillar somewhat displaced inwards and sloping backwards. Well developed pterygoid wings. Internal nares limited anteriorly by the palatines, but situated mostly in the pterygoids. Mandibular symphysis relatively long, with the splenials taking part in it. Mandible slightly expanded anteriorly, with third and fourth alveoli large and continuous. Long retroarticular processes. Teeth pointed and slender. Vertebrae amphicoelias. Cervical vertebrae bearing well-defined hypapophyses. Dorsal and ventral armour well developed. Dorsal scutes bearing an anterolateral peg and two longitudinal ridges. Ventral scutes hexagonal. Forelimbs long, with all segments elongate and slender, especially the carpal bones.
