Fossiliferous strata near Lake Titicaca (Bolivia)

I lived several years in Bolivia, doing botany, ethnobotany, agronomy and agriculture. On december 28th, 1998, travelling in my car with my family around Lake Titicaca, I took these pictures of magnificent fossiliferous marny strata on the side of the road between the strait of Tiquina https://en.wikipedia.org/wiki/Strait_of_Tiquina  and Copacabana (Tiquina is between Huarina and Copacabana), on the bolivian southern side of the lake. Geologically, this area seems to belong to Devonian. And to the Gondwana, of course. A pretty good trip in the space and time...

What do paleontologists think about this ? As being not, it would interest me. Thanks in advance for your remarks.

* I remember that In the 1990' and 2000', one could purchase in the streets of La Paz, as I saw it many times,  fake Trilobits made of black terracota by Aymara people (traders in the soul and skilful crafts men) very, very nice and accurates and certainly made by moulding. This kind of geological site was perhaps a source o inspiration for them...
