Africa's oldest dinosaurs reveal early suppression of dinosaur distribution.

The vertebrate lineages that would shape Mesozoic and Cenozoic terrestrial ecosystems originated across Triassic Pangaea. By the Late Triassic (Carnian stage, ~235 million years ago), cosmopolitan 'disaster faunas' (refs. ) had given way to highly endemic assemblages on the supercontinent.

A Dynamic Anesthesia System for Long-Term Imaging in Adult Zebrafish.

Long-term in vivo imaging in adult zebrafish (i.e., 1-24 h) has been limited by the fact that regimens for long-term anesthesia in embryos and larvae are ineffective in adults.
