I wanted to modify the top surface of the dinosaur to be spikey, so I edited a duplicate surface of it and made adjustments that way. Now it seems like I’m having troubling fitting this surface back due to the modifications I made (even though its still the same shape). Would anyone know how I can do this? I tried merging with the use of shift V and bridging edge loop, but neither is working out.
Here is the one with surface detached.
