Solving an 85 Million-Year-Old Puzzle — Excavating An Elasmosaur

A mighty marine reptile was excavated on the Trent River near Courtenay on the east coast of Vancouver Island, British Columbia, Canada. The excavation is the culmination of a three-year palaeontological puzzle.
The fossil remains are those of an elasmosaur — a group of long-necked marine reptiles found in the Late Triassic to the Late Cretaceous some 215 to 80 million years ago. In the case of the Trent River, it is closer to 85 million years old. The marine reptile fossil was excavated 10-meters up high on the cliffs that line the river. It took a month of careful planning, building scaffolding, and amassing climbing gear to aid the team of dedicated souls in unearthing this juvenile elasmosaur. 
Bits and pieces of him have been eroding out for years — providing clues to the past and a jigsaw puzzle that has finally had the last pieces put together. The first piece of this marine reptile puzzle was found three years ago.
