Making insights into ancient marine ecosystems with 3D-printed shells

If you’re a snail hoping to survive an encounter with a hungry fish, it helps to have a strong shell. Paleoecology doctoral student Erynn Johnson is using 3D printing to understand how predator-prey interactions may have played out hundreds of millions of years ago.

Dry conditions may have helped a new type of plant gain a foothold on Earth

Plants reap energy from the sun using two photosynthesis pathways, C3 and C4. A new study led by Haoran Zhou, Erol Akçay and Brent Helliker suggests that water availability drove the expansion of C4 species, which may help to explain how different plant lineages came to be distributed on the planet today.

Tracing the evolutionary origins of fish to shallow ocean waters

Coral reefs are envisioned as the seats of great biodiversity, but they may not be where all that diversity got its start. In a new study in Science, paleobiologist Lauren Sallan and colleagues reveal that the earliest fish may have diversified in shallower waters near shore.
