Earliest short-tailed bird from the Late #Jurassic of China nature.com/articles/s41586-024

"The newly identified bird, called #Baminornis zhenghensis, joins the similarly aged #Archaeopteryx as the oldest-known #birds. But Baminornis, about 15 cm long, was far more advanced anatomically and a better flier than crow-sized Archaeopteryx, a creature seemingly half #bird and half reptile."

UK’s largest dinosaur footprint site unearthed in Oxfordshire quarry A unique discovery has brought to light the largest dinosaur trackway site known in the UK, found in Dewars Farm Quarry in Oxfordshire. More than 200 well-preserved dinosaur footprints, which are around 166 million years old and are from the Middle Jurassic Period, have been uncovered. The footprints were first identified by quarry worker Gary Johnson while clearing clay from the quarry floor. The tracks belong to two distinct species of dinosaurs. Four trackways were created by enormous herbivorous sauropods, likely Cetiosaurus, which could reach lengths of up to 18 meters. Their rounded, elephant-like footprints are a testament to their immense size. The fifth trackway is attributed to a carnivorous theropod, Megalosaurus, a predator that measured up to nine meters in length and left distinct three-toed, tridactyl tracks.
