The first synovial joints developed in the piscine jaw of ancestors of modern lungfish by an evolutionary process that modified preexisting fibrous and cartilaginous joints, which were the predominant articulation of the early sea- and land-dwelling vertebrates.[well established][VHOG] synovium AEO:0000181 EFO:0001393 synovium of articular capsule of synovial joint stratum synoviale
