We have our first macronarian today and no, no this is not in fact good news. Just wait until we get to titanosaurs. The pain we are all about to feel... Just ask @fezraptor. Anyway. Abrosaurus is an indeterminant macronarian from the Dashanpu Quarry in Sichuan Province, China, living in the Bathonian to Oxfordian ages of the Middle Jurassic, somewhere between 167 and 157 million years ago. Its skull had large openings only separated by thin struts, leading to its name; it is known from a nearly complete skeleton and fragmentary skull. It was about 9 meters long and fairly small for a sauropod. It exhibited the typical macronarian sauropod body plan, electing for increased height rather than increased length.
