The fossils of these two types of martian insects were seen on library computer viewscreens in the first season of Star Trek: The Next Generation without any description. The okudagram images were taken from the Spaceflight Chronology. In the book, the insect remains were described as silicon-based lifeforms about three centimeters long. Their age was silicon isotope dated to be several million years. The fossils were discovered after they were uncovered by a sandstorm in the year 2021. This date of discovery of a silicon-based lifeform would contradict the fact that silicon-based life was considered only a theoretical possibility until 2267, as established in TOS: "The Devil in the Dark".
