Re: fossilization chances
No, my argument is first, evos tried to pass off Pakicetus as semi-aquatic. That was later disproven, but by then they had gotten this into all the popular literature and textbooks, TV shows, all the usual indoctrination sources, that this was the first whale.
So they had to keep maintaining the bogus claim somehow, maybe they even believe it having so much invested into the claim.
So despite not really sharing any of the major characteristics of a whale, they go ahead and call it a whale. Heck, all they have is a claim that the ear is a forerunner of whale ears. The creature's ears certainly are not whale ears, and there is no evidence at that stage they were adapted for hearing underwater, just that perhaps there is the beginning of adapation for that.
Heck, why not call hippos, deer, or heck, people are whales too!
Yippee!

Ummm... news to me. It seems current evidence has it that pakicetus was an ancestor of the modern whale. No one ever called it the first whale. If they did the language is loose.
Pakecetes is the first known ancestor to modern whales.
Further, your nitpicking. Fact is, the creature is still a cetacean, the data on it was updated. It's legs were different than anticipated but by no means does that knock it out of Order Cetecea.
So despite not really sharing any of the major characteristics of a whale, they go ahead and call it a whale. Heck, all they have is a claim that the ear is a forerunner of whale ears...
No... Only an adaptation SPECIFIC TO CETACEANS. And I listed other characteristics it posseses as well
Heck, why not call hippos, deer, or heck, people are whales too!
LOL!
So ya, Dogs and Walruses are in the same order. They don't look anything alike.
What's the problem with Pakecetids being in the same order as modern whales?

Re: fossilization chances
Here is an extremely biased evolutionist site describing the common features of cetaceans. I say extremely biased because they list as vestigal limbs inside the whale when in reality they are vital to being able to mate, and not vestigal at all.
But nevertheless, they do list many of the common features of all cetaceans.
Please go through them and tell us which of these traits Pakicetus unequivcally shares.
All cetaceans share a number of similarities: they have a fusiform, or streamlined body shape; paddle shaped front limbs; vestigial hind limbs (which are within the body wall); no external digits or claws; tail flattened laterally and bearing horizontal flukes at the tip; vestigial ear pinnae; basically hairless body (some young have hair on their snouts); thick subcutaneous blubber layer filled with fat and oil; telescoped skull bones; external nares (blowhole) on the top of the head; addition of compressed vertebrae; shortening of the neck; lack of sweat glands; internal reproductive organs; 3-chambered stomach; and an airway reinforced with cartilage down to the alveoli. Many of these characteristics are adaptations to reduce drag for fast swimming in an aquatic environment. Protuberances such as external ears or genitals would create turbulence and would be very inefficient for an animal in the water.

Your description deals with modern cetaceans. Ancient cetaceans are beyond the scope of the article.

Is pakicetus a whale?
In fact, I found this lovely quotation (sorry if someone has already posted this):
Pakicetids were the first cetaceans, and they are more primitive than other whales in most respects. In fact, they did not look like whales at all, and did not live in the sea.

Re: fossilization chances
No one ever called it the first whale.
How many times on this thread do I have to post the exact same thing to show the exact false claim of an evolutionist to be wrong?
Pakicetids were the first cetaceans, and they are more primitive than other whales in most respects.
http://www.neoucom.edu/DEPTS/ANAT/Pakicetid.html
Pakicetus, shown above right, is a Middle Eocene archaeocete from the Kuldana Formation of Pakistan; it is currently the earliest known well-preserved cetacean,
Cetaceans
Pakicetidae
The First Whales ...Pakicetids were the first cetaceans,
http://www.neoucom.edu/...Thewissen/whale_origins/index.html
Are you satisfied your claim is 100% wrong, that evos do claim Pakicetus is a whale, and in fact Thiessen here calls it "the first whale"?
In the future, please read the darn thread. You are not the first one on this thread to make this false claim.

Here are quotes that prove otherwise, or they prove that evolutionists stated Pakicetus was aquatic or semi-aquatic. If they didn't think that, were they lying?

Pakicetus, shown above right, is a Middle Eocene archaeocete from the Kuldana Formation of Pakistan; it is currently the earliest known well-preserved cetacean, and the archaeocete features are clearly visible in this replica skull from UCMP's collections. Pakicetus is so far known only from its skull, but recent finds in Pakistan have produced other whale species that show very primitive characters in both the skull and the rest of the skeleton. These animals had relatively well developed limbs, but were aquatic.
Cetaceans
As has already been mentioned to you, you have misunderstood the subject (they) of the adjective "aquatic". To confirm, let's look at the immediately following sentences:
quote:
Below right is a drawing of the known skeleton of Rodhocetus, a recently discovered archaeocete from Pakistan, a few million years younger than Packicetus. Rodhocetus had well-developed hind limbs (although only the thighbone, or femur, has been preserved), but unlike land mammals, Rodhocetus did not have its vertebrae in the pelvic region fused together into a sacrum.
"They" and "These animals", the aquatic ones, refer to Rodhocetus.
Further citation of this reference as supporting your statement that scientists asserted that Pakicetus was aquatic or semi-aquatic would force one to consider that you are quote mining and being intellectually dishonest.

Re: fossilization chances
Please answer the question.
How many cetacean features listed here as common to all cetaceans does Pakicetus share?
Does Pakicetus even share one single feature that is exclusively whale-like?
It appears to me, at best, Pakicestus may have been developing an ear more whale-like, or maybe just had a different ear not homologous to whale ears at all. There is absolutely no way to tell/
Other than that, which is only half a whale-like feature or less, what other ways does this somewhat canine or rat-like looking creature resemble a whale?

Re: fossilization chances
I am sorry, but "they" in English would refer to the specified creatures before the sentence.
For example, let's say I am talking about a group of football fans, and I say college football fans love to go to Saturday day-time games. It is a big event. They usually drive but often that does not prevent them from drinking at parties before and afterwards. Soccer fans, although they like to drink too, often do something football fans don't. They like to sing.
Now, clearly the "they" refers in both sentences to the groups immediately references before the use of the term "they", not the groups afterwards.
That's how English works. So what you "showed" is wrong.
So perhaps you are being intellectually dishonest because everyone knows the rules of grammar, that the use of "they" refers to the specified group indicated prior to the use of "they" in such a paragraph.
If you want to say it is poorly written and that they intend on not counting Pakicestus as aqautic, fine. But you are trying to impugn my integrity here, and I don't appreciate it.
The first drawings showed Pakicetus as swimming when it was introduced, and so it appears to me that the web-site is picking up on that.

Re: fossilization chances
Those folks are using the terminology loosely. They are the first known whales. They call them first whales in the article because they are the first known whales. It's implicit.
They could allways find an earlier or a futer specimin. You are incorect.
No adress my previous point.

The article you mentioned does not include ancient whales in it's scope.
Do you object to dogs and walruses being in the same Order?

Re: fossilization chances
More,
The artist’s reconstruction of Pakicetus on page 66 of the November 2001 issue of National Geographic looks very similar to a dog swimming underwater. However, the artist obviously did not take into consideration the fact that the fossil was found in an area containing fossils from terrestrial creatures such as snails. The fossil also was found in a region full of iron ore that was part of a land stratum, not an aquatic one. This ancient ancestor was discovered in 1983 by Philip D. Gingerich, who immediately claimed the find as a primitive whaleeven though he found only a jaw and skull fragments! So what makes National Geographic so sure this creature is a long-lost walking ancestor to modern whales? Chadwick stated:
What causes scientists to declare the creature a whale? Subtle clues in combinationthe arrangement of cups on the molar teeth, a folding in a bone of the middle ear, and the positioning of the ear bones within the skullare absent in other land animals but a signature of later Eocene whales (2001, 200[5]:68).
So from mere dimples in teeth and folded ear bones, this animal qualifies as a walking whale? Interestingly, the skeletons of Pakicetus published by paleontologists in Nature do not resemble the swimming creature featured by National Geographic (see De Muizon, 2001, and Thewissen, et al., 2001). National Geographic displayed the Pakicetus in a swimming position, obviously trying to sway the reader into believing that the fossilized jawbone and skull fragments represented an aquatic creature.
http://www.apologeticspress.org/articles/2066
You can see the initial illustration of Pakicestus here, homepage of the guy that discovered it.
Based on what we know today, these animals were probably less different than shown here, and the hands and feet reconstructed for Pakicetus probably looked more like those now known for Rodhocetus.
Philip D. Gingerich
What about the recently described pakicetid genera?11 The vast majority of the skeletal traits found in the complete skeletons are consistently unlike those of true cetaceans (ancient or modern). By no stretch of the imagination do we observe anything resembling a gradational trend of changes to true cetaceans:
‘Aquatic postcranial adaptations are pronounced in late Eocene basilosaurids and dorudontids, the oldest obligate aquatic cetaceans for which the entire skeleton is known, and therefore can be used to evaluate pakicetid morphology. Aquatic adaptations of basilosaurids and dorudontids include [nine features are listed]. Pakicetids display none of these features.’41
As if all this were not enough, the few pakicetid traits once believed unambiguously indicative of an aquatic or semi-aquatic transitional lifestyle, are no longer necessarily considered thus.42 Consequently, the already borderline-deceptive practice33 of sketching Pakicetus as a semiaquatic-adapted creature, in a very recent issue of National Geographic magazine,43 is all the more inexcusable. And it is creationists who are supposed to be the purveyors of inaccurate and outdated information!

Re: fossilization chances
Yaro, are you going to dodge the question or answer it?
The reasonable way to see if something is cetacean is to examine the features that qualify cetaceans as whales, and then see to what degree those features are found in the subject species.
I cannot find one single shared feature exclusive to cetaceans that Pakicetus has.
Can you?
You claimed I was arguing from incredulity. Obviously you were wrong.
Will you admit that?
In fact, I am the only one here even bothering to make arguments based on the data particular to cetaceans.
Why is that?
Could it be you cannot make an argument based on the data because you have no data to refute my claims? It appears your entire argument is to argue from analogies, distortions, false claims, etc,..and to ignore the scientific evidence completely.
Why is that?

mammalian teeth
So from mere dimples in teeth and folded ear bones, this animal qualifies as a walking whale?
Actually, teeth are a very good identification tool for mammals. In some cases, even the exact species can be identified from teeth; certainly genera and families are routinely identified from similarities in teeth. Taxonomists are very happy to have teeth.

I haven't dodged the question. You have been shown several times in this thread what similarities they have with each other. You have been shown reems of papers, research, evidence, etc. That documents it clearly.
I'm honestly just board with this. Your argument is from incredulity simply because you have been shown the evidence and chosen not to belive it without providing any valid reason or alternative explanation.
Pakecetus have several cetacean fetures aside from the ear. Read the site posted several times in this thread. The article you cited was a description of modern cetaceans, it didn't have ancient cetaceans in it's scope.
We are at post 25* at this point, and essentially you have driven it around in circles and into a ditch. Because as I recal we aren't even done establishing what the hell your point is.
