24th c. skeletal remains
Promellian script.
The Promellians were a technologially advanced reptilian race that were the cause of their own extinction during their long war with the Menthars, that ended with the battle at Orelious IX during the 14th century.
The Promellians operated advanced Promellian battle cruisers, which operated at a technology level that rated as rather crude in terms of 24th century Federation technology. They also used a form of information storage device that was a crude analog of a 24th century Federation isolinear optical chips. (TNG: "Booby Trap")
- Promellians bear a striking resemblance to the Algolians and another unnamed species
