He did mention two other examples
The other two examples - dogs/wolves and dinosaurs/birds are not forgeries.
The studies of fossils and remains, both past and present, show that it is highly probable that both dogs are descendants of the older species of the grey wolves or Canis lupus. Evidences showed that wolves were hunting with man, millennia before the first appearance of domesticated dogs (Canis lupus familiaris).
Dogs just didn't appear suddenly; they didn't come out of thin air, via magic or like Genesis 6th day. There are no evidences to show dogs existed before 15,000 years ago.
Some wolves remain wild, while those that remained with man, hunting with them, were selectively breed for specific purposes, became dogs.
Evidences showed that grey wolves have a longer history than dogs. The grey wolves have been around as early as the Middle Pleistocene (starting around 800,000 years ago), the oldest skeletal fossils, dating to between 700 and 600 thousand years ago.
As to dinosaurs and birds, i don't know much about, but as I understand it still actively undergoing been researched, and the evidences are there that the earlier species of birds did originate from certain genus and species of dinosaurs.
You need to understand bird-like creatures did exist before the Cretaceous period (which started around 145 million ago). No true birds exist before 120 million years ago, which is when you would find the earliest fossils of birds.
This actually put a crimp into Genesis 1, because according to Genesis 1:20-23, birds were created at the same time as fishes and other marine life, on the 5th day, before any land animals that walk or crawl.
But according to fossil evidences, the first dinosaurs appeared in the Triassic period (started around 250 million ago).
Not only that. The first true mammals appeared in the Triassic period too.
And the fossils to the earliest reptiles or the proto-reptiles, appeared around 312 million years ago, which put it in late Carboniferous era (Carboniferous started about around 359 million ago).
So the appearance of land animals, like the reptiles and mammals, over hundred millions of years before birds, only demonstrated that Genesis is wrong that bids exist before "land animals".
