The Byblos Fossil Museum — also called Memory of Time — is a small private museum housing an exceptional collection of marine fossils from the Lebanese mountains, many of them from the Cretaceous period (around 95 million years ago). The Lebanese limestone formations are world-famous among palaeontologists for the quality of preservation: fish, crustaceans, reptiles, and plant material are found in extraordinary detail, and the Byblos museum's collection includes some fine examples including large predatory fish with smaller fish visible inside them.
The museum is a family-run operation and makes a pleasant complement to the archaeological site next door — the geological timescale the fossils represent makes the 9,000 years of human occupation at Byblos seem rather recent. Entry is inexpensive and the displays are well-labelled. The same family also runs a fossil and mineral shop that attracts collectors interested in purchasing pieces from Lebanese quarries.
