I don't know what you mean by "land animals" -- maybe modern mammals? -- but the first land animals existed hundreds of millions of years before the first birds.
It specifcally mentions cattle and beasts of the earth. It says creeping things but does not specifically mention anything like lizard or serpent. That's open to interpretation. Where do snakes fit in? Are they reptiles that lost their lega or did they come first and legs develop later? Or is there no good fossil record of this? I imagine that snake skeletons are pretty fragile.
