SFT-S01E08-Spider Inc

Science Fiction Theatre is an American science-fiction anthology series syndicated and broadcast from 1955 to 1957. It was produced by Ivan Tors and Maurice Ziv. A total of 78 episodes was produced.
Opposite to what happened during the 1950s, the first season was filmed in color, but to cut production costs, the second season was filmed in black-and-white.
Science Fiction Theatre was a predecessor to later science-fiction anthology shows such as The Twilight Zone and The Outer Limits.
Episode 8 of the first season: Spider Inc
A young geologist discovers an ancient spider enclosed in a piece of transparent rock.
