The problem is that one is two teeth from South America and the platypus has no teeth. Tell me how did that lineage get established? Through evo-super molecular analysis of non-existent DNA? Also, kindly tell us the proof that these species had the following traits:
1. the mammary glands.
2. the egg laying.
3. your 3 earbones.
4. the poison spur.
5. the duck like bill.
6. the webbed feet.
7. the toothless mouth.
8. the electro-sensor in the bill.
9. the fur.
10. the cloaca.
11. the ability to vocalize and make different sounds.
In addition, if you insist that those teeth had the traits mentioned, then you need to tell us from what specific species these Obdurons got the above traits.
Creationists trying to discredit a fossil for showing the very transitional character demanded by creationists in the first place is just another old-hat game. Gish attacking Pakicetus for having fully terrestrial legs--"What kind of whale is that?"--comes to mind.
In other words, if the "ancestor" species offered as evidence of evolution is notably different from the descendant, scoff and demand transitionals. Do this no matter how many proposed ancestors form the chain and how logical the sequence may appear.
Of course, if the difference is imperceptible between ancestor and descendant, scoff and say so. Either way, you get to scoff.
You scoffed away the reptile-to-mammals skull series, claiming that the author of the article had simply done a lot of creative drawing. (Did he make up all the references to the paleontological literature too?) Funny, there's this overwhelming pile of evidence, but gore simply waves hands, calls a few people liars and fakers, and it's all gone--at least from gore's mind. But there's a separate line of evidence that Cuffey didn't tie in and of which I for one was unaware at the time.
You know how we can see the reptilian jaw reforming to become the mammalian earbones, in nice easy stages, in the fossil record? You can see the same thing happening in mammalian embryos, pigs and humans that I know for sure.
I pinged you on another thread about this after I linked some articles, but you didn't answer.
