specimen

A more complete specimen of Wapuskanectes betsynichollsae. TMP2012.50.1. (A) Dorsal view of the originally upside down remains recovered from north of the town of Fort McMurray, Alberta. The head and most of the neck were lost when intercepted by a grader during road construction. The right flipper was lost sometime in the Early Cretaceous prior to the final burial of the body. (B) The pelvic and abdominal regions of TMP2012.50.1 showing gastroliths (black arrows) within the body cavity that settled between the ribs of the inverted carcass and hint at a more substantial collection that is hidden inside the body cavity. Scale bars on body regions are 10 cm. Source credit: Sue Sabrowski, Royal Tyrrell Museum of Palaeontology.

Reconstruction of the skull of Lagenanectes richterae in right lateral view. Only the anterior part of the skull and lower jaw is preserved in the type and only known specimen. The posterior parts are reconstructed based on the related genus Libonectes.

MUHNCAL.20173, holotype specimen of Gondwananectes osvaldoi. A, quarry scheme of the recovered blocks (numbered 1–7). Blocks 1–3 preserve contact surfaces and they are arranged consistently. The position of blocks 4–7 is tentative due to the lack of contact surfaces, although it is based on the anatomical elements preserved. B, schematic diagram of the preserved anatomical elements in MUHNCAL.20173. Abbreviations: c1–c10, cervical centra/vertebrae; d1–d3, dorsal centra; d1na–d3na, neural arches of the d1–d3 dorsal centra; il, ilium fragment; in, indeterminate; lco, left coracoid, lcna, last cervical neural arch; lh, left humerus; lsc, left scapula (ventral process); p1–p2, pectoral centra; pd, posterior dorsal centrum; pna, pectoral neural arch; r, ribs; rh, right humerus (distal); rsc, right scapula (dorsal process). Scale bars represent 10 cm.

Meyerasaurus victor (jr synonym Rhomaleosaurus victor) holotype. Specimen # SMNS 12478, Museum am Löwentor, Stuttgart, Germany

A color-coded skull diagram of Palatodonta bleekeri, mostly based on a diagram published by Neenan et al. (2013). Some interpretations (such as the presence of a quadratojugal) are based on Maisch (2020). Depicted in left lateral view, mirrored from the original specimen as preserved in right lateral view. Dotted lines indicate missing bone.

Ferrodraco lentoni gen. et sp. nov. holotype specimen AODF 876. All preserved elements were photographed and scaled to the same size, then articulated where possible. These were then used as the basis for the scaling of the skeletal reconstruction, the missing parts of which were based on the skeletal reconstruction of Tropeognathus mesembrinus by Mark Witton. Scale bar = 50 mm.
