Thank you DrJeckyll for your response.

The 3rd part is actually important and cannot be removed from the thesis and even though it has nothing to do with my research, so far I am writing in the discussion that further study and re-examination should be undertaken of some wood samples to make sure they belong to the period they are assigned to...

That is how far I can go with it at the moment, but if anyone has more ideas of how to approach this issue I will truly appreciate it.

Greetings to all,

After 4 years of work I am now at the final stage to complete my PhD, in Palaeontology, I will be submitting my thesis in a month and getting ready for the VIVA.

My research is based in the Cretaceous climate and biosphere conditions, and it is divided in 3 main parts:

In the first 2 parts I used 2 different methods and the results were positive. The last part consisted of a microscopic analysis of an initially Cretaceous wood that my supervisor provided me enthusiastically, and was showing good results. However, at the very end of my analysis I found that such fantastic wood was from the Neogene period, and hence I could not use it in my study about the CRETACEOUS climate.

I speeded 1&1/2 years studying the wood sample, and after the terrible finding I had no time to analyse another wood and had to focus on writing the thesis.

I have now almost completed the writing, but I am having trouble with the discussion, because it's to hard for me to link the first 2 parts with the 3rd one and finding a way to making it look reasonable. I do not know how to discuss my findings about a wood that shouldn't have been used in the first place.

My supervisor is a super busy Doctor, who hardly ever writes a feedback and just seems now trying to push me out of the office, as if 4 years of work is long enough to submitt and go.

Could anyone provide me with an advice to how should I conect all my results together (including the alien wood)? And how should I defend the titled of my thesis when the material used for one of the analysis is not appropriate and cannot support it?

Thanks so much in advance.
