Figure 12 in A new Berriasian species of Goniopholis (Mesoeucrocodylia, Neosuchia) from England, and a review of the genus

Figure 12. Phylogenetic analysis of Mesoeucrocodylia, with emphasis on Goniopholididae. The topology is the strict consensus of two trees, and major clades are summarized by thick lines (proportional to the number of specimens included in the analysis). The family Goniopholididae is indicated by the light grey box, whereas the genus Goniopholis is indicated by a dark grey box. Note that 'pholidosaurids' in their traditional sense are paraphyletic (dotted box), but Sarcosuchus, Elosuchus, and Vectisuchus constitute a monophyletic group (i.e. Elosuchidae). Nodal support is given for each node (Bremer decay/bootstrap/jackknife), but bootstrap and jackknife are only shown for values above 50%.

Figure 8. Dorsal view of skull at orbits, showing the periorbital structures of Goniopholis kiplingi sp. nov. DORCM 12154. The extreme elongation of the lachrymals (left) is one of the autapomorphic characteristics of this species. On the right, detail of the orbit and surrounding structures (indicated only at the lower image). In the left image, a putative bite mark is indicated at the anterior end of frontal, near the triple contact with nasal and prefrontal. Note the lachrymaljugal suture next to the orbit, and inside the lachrymal indicated by the white pointer. Scale bars = 20 mm. Abbreviations: BPO, postorbital bar; CLPO, lower periorbital crest; CUPO, upper periorbital crest; Fr, frontal; FST, supratemporal fenestra; Ju, jugal; Lac, lachrymal; Mx, maxilla; Na, nasal; Par, parietal; Po, postorbital; Prf, prefrontal.

Figure 9. Maxillary depressions of Goniopholis kiplingi sp. nov. DORCM 12154, with detail of the right structure in lateral view, showing its internal structure. Note that the area around the fossa is smooth, unornamented; and the interior is complex (see Andrade, 2009). The dorsal exposure of the right fossa is taphonomic; the structure faces laterally in other goniopholidids, and also on the left side of DORCM 12154. Common neurovascular foramina are indicated by white pointers. Scale bar = 20 mm. Abbreviations: Ju, jugal; Mx, maxilla.

Figure 3. Sample of European goniopholidids included in this study. A, reconstruction of Goniopholis simus, as interpreted from our examination of specimens. B, Nannosuchus gracilidens BMNH 48217 (type). C, Hooley's specimen BMNH R3876, erroneously referred to Goniopholis crassidens. D, Dollo's specimen IRSNB R47, erroneously referred to G. simus.

F, Vectisuchus leptognathus SMNS 50984 (type), often referred to Goniopholididae, but actually showing closer affinities with Elosuchus (see the phylogenetic analysis herein). Note that maxillary depressions are absent in Nannosuchus and Vectisuchus. Scale bars = 20 mm. Drawings not to scale.

DORCM 12154 in its original slab (A), showing general aspect and material directly associated (indicated by white pointers): B, turtle scute; C, coprolite; D, bivalve.

Figure 5. Goniopholis baryglyphaeus MG 'Gui Croc 1' (type). The skull is heavily damaged and composed of fragments, but the bony surface is well preserved. The ornamentation is intense, and almost completely composed of pits. Note that the skull is divided in anterior and posterior sections, and only parts of the premaxillae are preserved. The transfrontal crest is indicated. Scale bar = 20 mm. Abbreviations: FLT, laterotemporal fenestra; FoMX, maxillar fossa; Fr, frontal; Ju, jugal; Mx, maxilla; Par, parietal; Pmx, premaxilla; Po, postorbital; Qj, quadrate-jugal; Sq, squamosal.

Figure 14 in A new Berriasian species of Goniopholis (Mesoeucrocodylia, Neosuchia) from England, and a review of the genus

Figure 14. Phylogenetic relationships of Goniopholididae and other main groups of neosuchians, calibrated through time. The goniopholidid fossil record begins in the Early Jurassic, but most members of this group occur from the Late Jurassic to the Early Cretaceous (pre-Aptian). Calsoyasuchus is the oldest taxon, and appears as the basal-most goniopholidid. Denazinosuchus is the most recent record (Late Cretaceous), but its relationships are poorly understood. Dashed ranges represent variation in the age attributed to the material; grey/red ranges are uncertain records; dotted lines represent taxa of uncertain relationships. Abbreviations: Ng, Neogene; Q, Quaternary.

Figure 13 in A new Berriasian species of Goniopholis (Mesoeucrocodylia, Neosuchia) from England, and a review of the genus

Figure 13. Miscellaneous problems in 'goniopholidid' evolution, summarized by strict consensus. In the first additional analysis (A), the exclusion of Nannosuchus (= 'Goniopholis' gracilidens) leads to a less resolved topology, affecting the putative relationships of tethysuchians, but not goniopholidids. In the second additional (exploratory) analysis (B), the relationships of Denazinosuchus (= 'Goniopholis' kirtlandicus) are poorly defined and its presence also induces collapse of the tethysuchian taxa; although Denazinosuchus nests well inside Goniopholididae, it never clusters with Goniopholis. The third additional analysis (C) shows that the relationships of 'Goniopholis' phuwiangensis are also poorly defined, but the taxon nests inside a Sunosuchus-Eutretauranosuchus clade, rather than with any Goniopholis. In the fourth additional analysis (D), the putative assignment of 'G.' phuwiangensis is tested for the genus Siamosuchus (composite terminal with Siamosuchus phuphokensis, both from Phu Phok Formation, Thailand), which results in a poorly resolved topology, showing that there is no support for this combination. Terminals added in each topology are in bold; nodes affected are indicated by a grey arrow. Data on Thalattosuchia include 14 terminals, and are represented by a thick line.

Figure 2 in A new Berriasian species of Goniopholis (Mesoeucrocodylia, Neosuchia) from England, and a review of the genus

Figure 2. Provenance and geological settings of Goniopholis kiplingi sp. nov. The holotype DORCM 12154 was found in a crumbling cliff (right) at the north end of Durlston Bay, near Swanage. The outcrop is part of the Jurassic Coast of England, and is considered a Natural Heritage Site. This is the first British specimen of Goniopholis to have its precise stratigraphical provenance identified to the exact bed (129b, Intermarine Beds), which is indicated by an arrow, on the right.

Figure 7. Premaxillae and perinarial structures of Goniopholis kiplingi sp. nov. DORCM 12154. A, oblique view of the specimen, making evident the deep anteronarial notch, perinarial crests and postnarial fossa.

Figure 11 in A new Berriasian species of Goniopholis (Mesoeucrocodylia, Neosuchia) from England, and a review of the genus

Figure 11. Dentition of Goniopholis kiplingi sp. nov. DORCM-12154. A, ventral view of the right alveolar margin at the premaxilla-maxilla notch, showing the position of the fifth premaxillary alveolus (as indicated), which is lateral relative to the first maxillary tooth. B, detail of the fourth maxillary crown (right side). C, detail of third premaxillary crown (left side). Both teeth are not completely erupted, and have a mesial-distal keel. The intense ornamentation creates a crenulated edge, as it covers the keel, producing a false-ziphodont serration, in this case visible even without the aid of optical resources. Scale bars = 10 mm.

Figure 10. Distal end of skull of Goniopholis kiplingi sp. nov. DORCM-12154. The quadrate (left) is robust, but its dorsal surface smoothly progresses towards the posteromedial surface, where a foramen aerum can be seen, as indicated by the white pointers. A secondary opening to the foramen, at the dorsal surface of quadrate, is also indicated. In occipital view (right), the specimen is very similar to Goniopholis simus, with the cranioquadrate passage mostly covered by the paraoccipital process, as indicated by the arrow. Scale bars = 20 mm. Abbreviations: Ex, exoccipital; PaCQ, cranioquadrate passage; Par, parietal; PPoc, paraoccipital process; Qj, quadrate-jugal; Sq, squamosal.
