01 / DEFINITION & ECOLOGY
What was Mamenchisaurus?
Mamenchisaurus (Mamenchisaurus hochuanensis) was an extinct organism known from About 160–155 million years ago, with a range in Lake and river woodland · Southwestern China.
Life and ecology
Mamenchisaurus swept its neck across a large feeding envelope without moving its heavy body often. Its neck was mobile but not always held swan-like and vertical.
02 / DISAPPEARANCE
Why did Mamenchisaurus disappear?
Asian environments and sauropod lineages changed near the Jurassic's end, and the extreme mamenchisaurid design declined.
03 / EVIDENCE
How do scientists know about Mamenchisaurus?
A near-complete skeleton preserves the neck, shoulder and tail club; CT and proportions constrain neck mass and mobility.
