Well, on the third day, God created the plants, and on the fifth day, animals appeared, (with “livestock according to their kinds”, whatever that means, showing up on the sixth day, along with man) at least in the first story. This assumes that you, as I do, subscribe to the “two creations” interpretation of the first couple of chapters of Genesis, i.e., that since the two chapters describe the creation in different orders, they are in fact the Creation stories from two different traditions, concatenated in Genesis by the original collector of writings.
If you buy the idea that the first story used some connotation of the word “day” that does not directly imply a 24-hour period between sunrises (especially since the sun wasn’t created until the fourth “day”), you could conceivably conclude that the ages of Fishes, Insects, Amphibians, Reptiles, and the early part of the Age of Mammals all took place between the third and fifth days.
The sixth day marks the appearance of the creatures familiar to us, and man’s emergence as well. So not much inconsistency there, as long as you are VERY broad in your interpretation.
All of the above, of course, assumes that you have a deep need to have the Bible consistently and completely describe the world as it has been observed since it was written.
If you believe, again as I do, that the Bible is simply yet another culture’s mythology, fit to sit on the shelf next to Ovid’s Metamorphoses, the Norse sagas, and other such works, then it doesn’t really matter.
