The fossil record shows that this is likely to be the case, first in the retention of spore-like packets attached in short linear chains (e.g., Fig. 3B), but more substantially in sheets of paired spore-like cells, as seen here in Grododowon orthogonalis Strother 2017 (Fig. 4, A and B, and fig. S2J).The fossil record is a book with lots of pages missing. Entire species are lost to memory as rocks erode and change. Darwin believed that some of these gaps might never be filled—the fossil record is just too incomplete. One of these “gaps” was understanding how limbed animals moved from the oceans, where it was plentiful and … A diagram shows three rock layers. The top layer is labeled shallower.
