Keep in mind that a LOT of text was recovered from that era, and even before that era, it wasn't until computers could do rosetta stone-like translation that a lot of the more ancient papyrus could be extracted. A lot of it is partially congruent with either the Talmud or the Old Testament (who knows what the explanation is but there were probably many sects who each passed on different cannons). Also, the Vatican has a lot of text digitized now (they hoarded it forever) that isn't in line with the Council of Trent's canon.
The Dead Sea Scrolls proved the Old Testament was preserved intact since before the birth of Christ.

I think a lot of Hebrew and Zoroastrian (the pre-Islamic religion of mesopotamia and persia) cannon mixed especially near Cestiphon because of the Romans, Sassans and Greek influences: https://en.wikipedia.org/wiki/Zoroastrianism https://en.wikipedia.org/wiki/Alexandria_Eschate
In modern times (the last 20 years), a lot more text has been recovered from places far flung like Ethiopia, India, and even China.
