Omnilingual

"Omnilingual" is an unusual sci-fi story as it focuses on archaeology on an alien culture. An expedition from Earth to Mars discovers a deserted city, the remains of an advanced civilization that died out 50,000 years before. The human scientists recover books and documents left behind, and are puzzled by their contents.
Earnest young archeologist Martha Dane deciphers a few words, but the real breakthrough comes when the team explores what appears to have been a university in which the last few civilized Martians made their last stand...©2017 Audioliterature (P)2017 Audioliterature

Only an H.Beam Piper fan might like this

Not much story here only expectation and curiosity drove me to finish listening. Sorry to say it wasn't worth the effort. Maybe this was to be the introduction to an unfinished novel?

Interesting

Interesting but I was expecting a different ending. I was hoping to learn what was the connection between the periodic table and what the Martians did that caused there extinction.
