New paper out! 🔬📝🌊🐬 Lambert et al. @naturalsciences-be.bsky.social report on a Middle Miocene dolphin cranium from the southern North Sea found in an excavation at the city centre of #Antwerp #openaccess doi.org/10.20341/gb....

Upper part of the figure: Partial cranium of Kentriodon cf. Kentriodon pernix RBINS M.2340, lower Langhian of Antwerp (Belgium), in right lateral (A) and left
lateral (B) view. C. Cranium of Kentriodon pernix USNM 10670, Burdigalian of Maryland (USA), in right lateral view, based on 3D model downloaded from Phenome10k. Stippled lines for suture lines. Scale bar = 100 mm.

Lower part: Partial cranium of Kentriodon cf. Kentriodon pernix RBINS M.2340, lower Langhian of Antwerp (Belgium), in ventral view (A) with detail
of two in situ maxillary teeth in ventromedial view (B, C). Stippled lines for suture lines interpreted based on preserved suture marks. Scale bar for
A = 100 mm.

Sampled section of the temporary outcrop Delhaize Plantin, northern wall along the Plantin en Moretuslei, Antwerp (northern Belgium).
A. Unit 1 (Kiel Member, Berchem Formation), Unit 2 (Antwerpen Member, Berchem Formation, where the kentriodontid specimen RBINS M.2340
was found), and Units 3–4 (Quaternary deposits). Scale bar = 1 m. B. Detail of the boundary between the middle–late Burdigalian Kiel Member and
the lower Langhian Antwerpen Member. Some vague white spots can be observed in the top of the Kiel Member, representing cross-section of
lithified Ophiomorpha burrows. C. Detail of Quaternary unit 3. Subtle cross-bedding can be observed between the lenses with reworked Neogene
shell debris. D. Other detail of the Quaternary unit 3, with high contents of reworked glauconite and fine climbing ripple lamination in the base.
Photographs taken on May 8, 2023.

Lithology and lithostratigraphy of the temporary outcrop Delhaize Plantin in Antwerp (northern Belgium). The kentriodontid specimen
RBINS M.2340 was recovered from the base of Unit 2 (Antwerpen Member, Berchem Formation). Abbreviations: Antw. Memb. = Antwerpen
