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.

 Cette fois-ci, nous examinerons une espèce unique de poissons préhistoriques qui nageaient dans les rivières et les lacs tandis que certains des plus grands dinosaures marchaient sur terre.  Découvrez Lepidotes ! Reconstitution à l'aquarelle de Lepidotes gigas par Christopher DiPiazza. Les Lepidotes étaient un genre de poissons osseux à fortes écailles qui vivaient dans ce qui est aujourd'hui l'Europe et l'Amérique du Nord au début du Jurassique, il y a entre 180 et 175 millions d'années.  Le genre a peut-être même persisté jusqu'au Crétacé inférieur, il y a seulement 115 millions d'années, mais
