All the layers are there. It is just that, for the layers of that time period, they were rotated / tilted so they are not horizontal, then they were ground off from above and below. So a huge amount is missing, but all layers are represented. I mention it in more detail in a comment further down. This diagram shows the area in question. It's layer B. https://play.google.com/books/...
