The evolution and role of the hyposphene-hypantrum articulation in Archosauria: phylogeny, size and/or mechanics?
(Royal Society Publishing, 2019-10-02)
Living members of Archosauria, the reptile clade containing Crocodylia and Aves, have a wide range of skeletal morphologies, ecologies and body size. The range of body size greatly increases when extinct archosaurs are ...
Porosity production in weathered rock: Where volumetric strain dominates over chemical mass loss
Weathering in the critical zone causes volumetric strain and mass loss, thereby creating subsurface porosity that is vital to overlying ecosystems. We used geochemical and geophysical measurements to quantify the relative ...
Spiculogenesis and biomineralization in early sponge animals
(Springer Nature, 2019-07-26)
Most sponges have biomineralized spicules. Molecular clocks indicate sponge classes diverged in the Cryogenian, but the oldest spicules are Cambrian in age. Therefore, sponges either evolved spiculogenesis long after their ...
