On Jul. 18, 2023, scientists reported that they had extracted, sequenced, and analyzed historical RNA from muscle and skin tissue of a ~130-year-old Tasmanian tiger (Thylacinus cynocephalus) preserved in desiccation at room temperature in the Swedish Museum of Natural History in Stockholm.

The results represent the first successful attempt to obtain transcriptional profiles from an extinct animal species, providing thought-to-be-lost information on gene expression dynamics.
