Unfrotunately, I don't think I can be too much help here. Not my area of expertise, at least.
On the page with more information, it looks like two different colour varieties are mentioned: Dark Yellow Brown and Light Red Brown. The picture of the page with more information looks to be the former (I think) and the picture of the page with less information looks to be the latter. If those colour changes are significant enough to warrant their own pages, both could potentially be kept, but some of the year-lines from the page with more information would have to be moved to the page with less information.
(EDIT: And if they are to be kept separate based on their colours, that difference should most certainly be added to the titles on both pages.)
However, most of the year-lines on the page with more information are also talking about errors (14/18 of the lines). Perhaps those ones shouldn't even be there to begin with…
