Mamenchisaurus (SciiFii)

Mamenchisaurus orientus (name meaning "oriental Mamenchi Ferry lizard") is a species of sauropod that originally lived during the Middle Jurassic in what is now China and was once extinct, but has been brought back from extinction by SciiFii and now lives in Cretaceous Park located in Sacramento, California. It is a herbivore like most sauropods, feeding mainly on leaves of ferns, cyacads, horsetails, conifers, and among other evergreen trees, but can sometimes feed on fruits and nuts. It has the longest neck of any known dinosaur, long enough for it to reach even the tall trees such as pine trees. It is a large sauropod, growing to be 85.3 feet (26 meters) long and weigh about as much as three bull African elephants. It is a social herd-dwelling animal, living in groups up to around 6-10 at a time in most cases, but can occasionally live in herds as much as around 25-30 if there's enough space and food for them. During mating seasons, males clash with other males by side-ramming and/or using their tail clubs until one backs down, that's when a winning male Mamenchisaurus gets a right to mate with any of the herds' females.
