The first discovery of Mesozoic DNA was claimed by Cano and his team (see video).[1] They claimed that they had extracted and sequenced two DNA fragments from a 120-135-million-year-old weevil (Lebanorhinus succinus).

One fragment was never put into any Gene database. It did appear in the original article.

Controversy Edit

Scientists in 1998 found that this sequence was more similar to fungal DNA than weevil DNA.[2]

A BLAST search against the entire GenBank shows it has 93% similarity with Meyerozyma guilliermondii and 91% similarity with Pichia guilliermondii. Both species are part of the yeast order Saccharomycetales.
