RE: It is not a scroll?
It is a codex — an ancient manuscript text in book form.
The Muratorian fragment is a copy of perhaps the oldest known list of the books of the New Testament.
The fragment, consisting of 85 lines, is a 7th-century Latin manuscript bound in a 7th or 8th century codex from the library of Columban’s monastery at Bobbio; it contains features suggesting it is a translation from a Greek original written about 170 or as late as the 4th century.
Both the degraded condition of the manuscript and the poor Latin in which it was written have made it difficult to translate. The beginning of the fragment is missing, and it ends abruptly.
The fragment consists of all that remains of a section of a list of all the works that were accepted as canonical by the churches known to its anonymous original compiler.
What kind of material is it written on?
So, it comes from the 7th century, and might be quoting works from 170 to 400. Not sure it represents what it is being claimed to. But most of this is faith, anyways.

So there is still room for doubt it seems.
I’ve read that the entire New Testament could be compiled from the numerous and accurate quotations and citings from the writings of the church leaders called the Early Church Fathers.
