Scantlings are not the list of all the materials etc.
It is the term used to describe the WIDTHS and DEPTHS of all the important parts of the boat's structural members: apron, knighthead, hog, floors, knees, beams, timbers, frames etc.
The scantling widths are referred to as the "sided" dimensions, the depths as the "moulded" dimensions.
Minimum specifications for scantlings are established by a number of sets of 'rules' for boat construction. A bit like the Building Regulations in the building trade that advise, for example, on the sizes of roof and floor beams, an so on.
By far the most important set of rules of scantling sizes in the UK boatbuilding industry are "Lloyd's Rules for Yachts and Small Craft". Another is Herreshoff's Rules which are published in Skene's "Elements of Yacht Design". And the Sea Fish Industry Authority "Rules for the Construction of Fishing Vessels" (separate volumes for timber, GRP and steel): scantlings can be read directly from tables using a single reference figure for each boat, and as you would expect, the results obtained are much heavier than for yachts.
The term was originally used to refer to the smaller pieces of timber used for packing cargoes of larger timber baulks in sailing ships. These were in those days always of high quality, durable timber and would be kept and used, in boat construction for the sort of parts mentioned.
As construction 'rules' became more standardized and widely applied, the term itself became adopted to mean the actual specified dimensions of these parts.

They are merely the dimensions of the various parts that make up the hull and other parts of the boat/vessel. When building there is a minimum that will be required to maintain the structure in all weather conditions.

Along with stone, mud and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials.

The dimensions of the structural parts of a vessel.
The dimension of a piece of timber used in construction (especially of a ship).
The dimensions of a ship's principle timbers, or the timbers themselves.
