🌎 380-million-year-old air-breathing fish fossil unearthed in Australia
Plus: Zero-gravity parabolic flights to connect Japan's Simojishima islands
It’s time to introduce a new species of ancient lobe-finned fish — thanks to fossils recently unearthed in Australia. The sleek creature has been described as having ‘unique biological features,’ including huge fangs and bony scales. We also now know these fish roamed Earth’s seas roughly 380 million years ago (the Late Devonian).
But what adds to the intrigue is the existence of large holes in the upper part of the fish's skull. These spiracular structures are believed to have aided in surface air-breathing, allowing the fish to take in air at the water's surface.

MUST READ
Scientists announce a new predatory marine creature that once thrived in what is now Australia when rivers flowed over the now-dry landscape. Fossil analysis reveals the newly discovered fish species named Harajicadectes zhumini lived 380 million years ago.
Large holes in the fish’s skull indicate air-breathing adaptabilities to supplement gill respiration. This makes sense considering the Mid to Late- Devonian times coincided with low atmospheric oxygen levels.
An international expedition, the MSM126 Jellyweb Madeira, will explore the enigmatic depths of the ocean around Madeira, Portugal. Central to the mission is the remotely operated vehicle, ROV PHOCA, dubbed the "Swiss army knife of marine research," with the capability to explore depths exceeding 6,500 feet (2000 meters).
Washington DC's 0-G Launch, a trailblazer in microgravity flight technology, and Japan's PD AeroSpace, renowned for space transportation, have signed a collaboration deal. The partnership aims to launch zero-gravity parabolic flights from Japan's Simojishima islands starting in 2024.
