The ontogenetic development of extant birds is characterized by rapid growth, bone fusion and an early onset of flight ability.In contrast, little is known about how these ontogenetic traits evolved in the bird stem lineage, and the available data pertains primarily to Enantiornithes.Here, we describe an almost complete skeleton of a juvenile euorn
Background: Fibrodysplasia ossificans progressiva is a rare autosomal dominant connective tissue disorder with a prevalence of 2 per million individuals.Activating mutation of ACVR1, a bone morphogenetic protein receptor causes ossification of extra-skeletal structures like ligaments, tendons, and aponeurosis.The characteristic findings are bilater
