Data Merging & Distributions

Hi Guys ,
I have a workbook consist of 71 worksheet ,

In the first column of each worksheet i have a unique serial number that duplicate for all rows in the same sheet

In the second column of each worksheet i have a date which take from like 12/31/2017

Now i need to delete all rows from all worksheet that contain these dates in second column
"3/15/2017" "3/27/2017" "5/17/2017" "9/13/2017" "12/5/2017"


As i said before each worksheet has unique serial number in first column EXCEPT the last worksheet "sheet 71"

"sheet 71" contain a mix of all unique numbers that exist in all other worksheet , now i would like to distribute the content of "sheet 71" to other sheets depending on Unique Serial Number

So matched Unique Serial Number will be the key factor for distibutions and merging data , How can i do that in a quick way ?

Thanks

A1 - Yes all rows in each worksheet have a date , and there is no empty cell in Second column
A2 - For all worksheet , Column L is the last Column
A3 - Yes its preferred to be empty but it's only one sheet and i can do this manually so , no problem with that issue

Thanks for your response Kev

I really appreciate your help in resolving the problem , and i will check out your answer tomorrow , Have a good night

The result for my first request is Awesome and Perfect .. it works fine and all deleted rows have been moved to "RowsDeleted" sheet .. now what's the next step to distribute rows of "sheet 71" to other worksheet ?

OK , take your time and i will post the second half of problem in new thread after marking this as solved
Thanks
