I can imagine that some discoveries are not made for a long time despite availability of all the information and tools that one would in principle need.
Are there clear examples of that?

To me the most striking example of an invention that could have been invented long before it did is the Antikythera mechanism (https://en.wikipedia.org/wiki/Antikythera_mechanism), a calculating machine that predates those of Pascal and Napier by almost 2000 years, but which was lost and forgotten, until its discovery in 1901. If this invention had become known before it sank at sea, the development of Science might have advanced several centuries ahead.
