Research

• A study on the ancestral activity patterns of mammals inferred from the activity patterns of extant mammals is published by Maor et al. (2017), who argue that mammals most likely originated from ancestors which remained nocturnal throughout the Mesozoic until either shortly before the Cretaceous–Paleogene extinction event or just after it (considered more likely by the authors).
• A study on the evolution of jaw muscles across the cynodont–mammaliaform transition is published by Lautenschlager et al. (2017).
• A study on the morphological changes to the jaw processes in the evolution of Mesozoic mammals (especially early cladotherians) and their implications for changes to the jaw muscle vectors and jaw rotation is published by Grossnickle (2017).
• Tracks of a small hopping mammal trackmaker are described from the Early Cretaceous Jinju Formation (South Korea) by Kim et al. (2017), who name a new ichnotaxon Koreasaltipes jinjuensis belonging to the morphofamily Ameghinichnidae.
• Tracks of a raccoon-sized mammaliaform representing the morphofamily Ameghinichnidae are described from the Early Cretaceous (late Aptian) Calonda Formation (Angola) by Mateus et al. (2017), who name a new ichnotaxon Catocapes angolanus.
• New specimen of the morganucodontan species Wareolestes rex (partial dentary) is described from the Middle Jurassic Kilmaluag Formation (Scotland) by Panciroli, Benson & Walsh (2017).
• A description of the morphology of the postcranial skeleton of Yanoconodon allini and a study on its implications for the posture and locomotion of members of this species is published by Chen, Luo & Wilson (2017).
• New fossil material of members of the genus Gobiconodon is described from the Early Cretaceous of Mongolia by Lopatin (2017).
• A multituberculate femur is described from the Upper Cretaceous (Maastrichtian) Maevarano Formation (Madagascar) by Krause, Hoffmann & Werning (2017), confirming the presence of multituberculates on Gondwana.
• A study on the anatomy of the skull of Necrolestes patagonensis, with emphasis on its adaptations to a fossorial lifestyle, is published by Wible & Rougier (2017).
• Vertebrae and fragmentary elements of the fore- and hindlimb of therian mammals are described from the Upper Cretaceous (Turonian) Bissekty Formation (Uzbekistan) by Averianov & Archibald (2017).
