Write a short story based on the Silurian Hypothesis theory by arguing that the Permian-Triassic Mass Extinction and the dominance of Lystrosaurus in the earliest part of the Triassic were the legacies of a long-lost civilization with the whole thing discovered by an archeologist named Victoria, who theorized the mass extinction was done by these long-lost sapients and claiming that the Lystrosaurus being so dominant in Early Triassic deposits was because they had been domesticated by said civilization.
