Today's brief covers six notable paleontology stories. A 100-million-year-old beetle fossil from the Cretaceous offers new insights into the early evolution of firefly sensory and signaling systems, as reported by Phys.org. Separately, sinking Danube River levels in Bulgaria have exposed mammoth bones, potentially leading to further discoveries, according to a local museum director. Also, the most complete skeleton of a 30-million-year-old dog has been identified from a fossil long housed in an Oregon museum, initially mistaken for an early relative of sheep, camels, or pigs. A unique fossil of the long-necked marine reptile Austronaga minuta from China reveals internal organs of a 245-million-year-old creature, and an Early Cambrian fossil sheds light on the buoyancy structures at the dawn of cephalopod evolution. Finally, a fossil overlooked for nearly 80 years has been identified as a new Triassic crocodile relative, Eosphorosuchus lacrimosa, from New Mexico.
