Synchrotron tomography of a stem lizard elucidates early squamate anatomy
Squamates (lizards and snakes) include more than 10,000 living species, descended from an ancestor that diverged more than 240 million years ago from that of their closest living relative, Sphenodon. However, a deficiency of fossil evidence1,2,3,4,5,6,7, combined with serious conflicts between molecular and morphological accounts of squamate phylogeny8,9,10,11,12,13 (but see...Tałanda, Mateusz ; Fernandez, Vincent ; Panciroli, Elsa ; Evans, Susan E ; Benson, Roger J

Postcrania of Borealestes (Mammaliformes, Docodonta) and the emergence of ecomorphological diversity in early mammals
The Middle Jurassic witnessed the early diversification of mammal groups, including the stem-mammalian clade, Docodonta. Recent discoveries in China indicate docodontans exhibited ecomorphological diversity akin to small-bodied mammals living >100 million years later, in the Cenozoic. Our understanding of the emergence of this ecological diversity is hindered by a lack...Panciroli, Elsa ; Benson, Roger B J ; Fernandez, Vincent ; Humpage, Matthew ; Martín‐Serra, Alberto …

New species of mammaliaform and the cranium of Borealestes (Mammaliformes: Docodonta) from the Middle Jurassic of the British Isles
Docodonta are one of the earliest diverging groups of mammaliaforms, and their morphology provides key information on the transition between non-mammalian cynodonts and Mammalia. We describe the partial skulls of two docodontans Borealestes serendipitus and Borealestes cuillinensis sp. nov. from the Kilmaluag Formation (Middle Jurassic: Bathonian), Isle of Skye, Scotland....Panciroli, Elsa ; Benson, Roger B J ; Fernandez, Vincent ; Butler, Richard J ; Fraser, Nicholas C …
