New Species of Triassic Carnivorous Dinosaur Identified in Argentina
A new genus and species of theropod dinosaur being named Anteavis crurilongus has been described by a team of paleontologists from the Universidad Nacional de San Juan, the Museo Argentino de Ciencias Naturales 'Bernardino Rivadavia,' the University of Birmingham, CONICET and CIGEOBIO.An artist’s reconstruction of Anteavis crurilongus.

This dinosaur was approximately 1.2 m (4 feet) in length and weighed about 8-9 kg.
The ancient species was an early-diverging theropod placed outside the dinosaur group Neotheropoda, but it had unexpectedly derived features previously thought to be exclusive to that group.
“It is one of the oldest and most primitive dinosaurs known so far,” said Dr. Ricardo Martínez from the Universidad Nacional de San Juan and his colleagues.

New Species of Bioluminescent Sea Slug Discovered
Top Stories Tamfitronics Marine biologists at Monterey Bay Aquarium Research Institute (MBARI) have described an exceptional sea slug (nudibranch) species, new to science, from depths of the eastern North Pacific Ocean. Named Bathydevius caudactylusthe species is bioluminescent and represents the third independent origin of bioluminescence among sea slugs.Bathydevius caudactylus has a voluminous hooded structure at one end, a flat tail fringed with numerous finger-like projections at the other, and colorful internal organs.
