Researchers discovered three distinct tanystropheid archosauromorphs, including a new genus and species, Akidostropheus oligos, from Triassic freshwater deposits at Petrified Forest National Park, highlighting diverse nonmarine ecosystems and potential defensive adaptations in these ancient reptiles.
A team of scientists has discovered a 22-million-year-old petrified mangrove forest on an island in the Panama Canal, dating back to the early Miocene period. The fossils and sediment samples collected from the island indicate that a volcanic eruption followed by a lahar covered the island with mud and rocks, preserving the ancient mangrove forest. The researchers have named the new tree species Sonneratioxylon barrocoloradoensis and suggest that it likely grew taller than modern mango trees due to higher levels of carbon dioxide in the air at the time.
