"Dinosaur Fossil Unveils Surprising Bird-Like Behavior"
A fossil of a small birdlike dinosaur, named Jaculinykus yaruui, found in Mongolia suggests that these dinosaurs may have exhibited birdlike behavior. The fossil was discovered in a sleeping posture similar to modern birds, with its head tucked over its limbs and tail wrapped around its body. This behavior was previously thought to be unique to birds but is now believed to have been more common among non-avian dinosaur relatives of early birds. The fossil represents a new species and provides valuable evidence of the sleeping posture in alvarezsaurids and early branching maniraptoran dinosaurs. The discovery suggests that this avian-like behavior evolved prior to the origin of powered flight and may have served as a thermoregulatory strategy.
