Read the following paragraph from the section "May Have Been Largest Turtle In History."

"For almost four decades, we didn't have new and excellently preserved fossils of this turtle," said Edwin Cadena. Cadena is a paleontologist at the Universidad del Rosario in Colombia. He is one of the study's lead researchers. Scientists first discovered the Stupendemys in the 1970s. Back then, scientists didn't have much information about the Stupendemys. They didn't know about what it ate, if there were differences between males and females or if there were possibly other species of giant turtle. Cadena and the other scientists have learned much more about the Stupendemys.

Which of the following is an accurate explanation of what this paragraph means?

A
Cadena and his team did not find out enough information about the Stupendemys 40 years ago.
B
Cadena and his team learned information about the Stupendemys that proved other scientists wrong.
C
Cadena and his team were the first group to find the Stupendemys fossils in the country of Colombia.
D
Cadena and his team found out more information about the Stupendemys than scientists did 40 years ago.
