thread_title:  Article deficiencies 

message: “Ambulocetus did not have external ears. To detect prey on land and in the water, they may have lowered their heads to the ground and felt for vibrations.”
“…and it [ambulocetus] shared ear structure with whales, enabling it to hear well underwater”
Don’t these two statements contradict to each other? Verdi1 18:20, 8 May 2006 (UTC)
replies: text: Changed the first statement to "To detect prey on land, they may have lowered their heads to the ground and felt for vibrations." Ambulocetus did lack external ears, instead it had a fatty hollow in its jaw that picked up vibrations, just like whales. Unless living whales routinely lower their heads to the seafloor in order to hear, the original statement is not accurate. 71.217.114.221 03:08, 21 January 2007 (UTC)
replies: text: The illustration that's adapted from the Nov. 2001 issue of National Geographic shows it incorrectly with ears then.  Maybe the picture should be removed. 69.226.74.4 02:08, 26 June 2007 (UTC)
thread_title:  Underwater hearing 

message: Is he really an anthropologist? Beside he dug out remains of ancient whale, he has too many publications on evolution of whales (not humans)? Who is that Mr. Thewissen at all? What is his nationality; in what year he dug out ambulocetus? Without all these the article seems incomplete. Verdi1 18:20, 8 May 2006 (UTC)
replies: text: He may be listed as an anthropologist by mistake--I often hear people say that archaeologists are the ones who dig up dinosaur fossils, it seems that people regularly get their ancient sciences confused, or simply don't know that there is a branch of science dedicated to extinct animals (whenever I mention paleontology to someone, their eyes go all glassy like I've just started speaking a foreign language). I really don't think the man's nationality has any bearing on the subject at hand, however. 71.217.114.221 03:03, 21 January 2007 (UTC)

message: So this animal is known to have tolerated both fresh and saline water, and its fossils were discovered in what used to be a coastal area. Could it be that Ambulocetus lived in an estuarine environment? 71.217.114.221 17:48, 24 January 2007 (UTC)

message: How many fossils were found?  Exactly which bones were found?  Please include this information or point me to where I can find it.  Thank you.  --Frankypenner 14:00, 10 May 2007 (UTC)
replies: text: I agree, this article is a great summary of conclusions but does not present enough findings, facts, or where to find them.
The link at the bottom of the page needs fixing: it is the one that shows a photo with the set of bones found

thread_title:  Fossils found 

message: The fossils that were found are quite inconclusive and the article is based on supposition and artists impressions. The following link will show what fossils were actually discovered. http://www.answersingenesis.org/tj/v8/i1/whale.asp  —Preceding unsigned comment added by 81.152.29.72 (talk) 16:12, 5 March 2008 (UTC)

thread_title:  Images 

message: "it was clearly amphibious, as its back legs are better adapted for swimming than for walking on land, and it probably swam by undulating its back vertically, as otters and whales do" - How is it that the back legs were better adapted for swimming? Please provide some detail.  If this is the view of the discoverer of this species, perhaps you can attribute it to him instead of stating it as a matter-of-fact.  
The assumption that this creature swam like a whale or otter seems to be from a desire to establish this animal as a precursor to whales. How do we know it didn't swim like a dog, horse or hippo? If there is more detail to reinforce your assumption, please share it.  Otherwise, it might be better to steer clear of such speculation.  — Preceding unsigned comment added by 207.181.15.206 (talk) 23:26, 2 November 2011 (UTC)
thread_title:  How do you reach your conclusions? 

message: There has been limited fossil evidence for this species. See Diagram:
http://www.foolishfaith.com/images/chap3_fossils_pic.gif
I know the website's topic is a bit controversial, but we must ignore the any bias here at wikipedia and just look at facts and findings. 
This page gives the impressions that there has been accurate fossil finds to this transitional species but many sources I have found says there is not. 
PLEASE, try and find any newer source (as mine is a bit old) of a fossil find for the Ambulocetus so we can say so with accurate proof.

text: Among other things, it's not that Wikipedia ignores bias, it's that editors at Wikipedia should ignore sources with a vested interest in spreading misinformation on particular topics, such as all Creationist sites that lie about how fossil whale skeletons are allegedly too incomplete to be informative about whale evolution.  Plus, this paper shoots a hole in foolishfaith.com's claim.--Mr Fink (talk) 21:12, 28 January 2014 (UTC)

replies: text: Whale fins are modified legs (and do look like small legs without the flesh), so I don't find it strange.  But I'd have to read more on this animal to confirm if the material is due.  —PaleoNeonate – 02:29, 28 June 2019 (UTC)

replies: text: It called a vestigial body part and is present everywhere. Why do humans have tailbones, male nipples, goosebumps, wisdom teeth, a third eyelid, grasp reflex or visible parts of our ears? Just because an organism doesn't need something doesn't mean that natural selection has worked the part away. It is one proof for evolution rather than for a grand designer who made all these imperfect organisms.--Akrasia25 (talk) 16:11, 29 June 2019 (UTC)
thread_title:   I don’t buy it 

message: Hey, somebody needs to fix the Fossil Range in the Taxobox. It says that Ambulocetus lived in the Cretaceous Period. Yet, it lived during in the Eocene epoch, around 49 to 48 million years ago.   
: For now at least. Someone keeps messing with the date and that resets the box. Thanks for noticing. --Akrasia25 (talk) 01:32, 20 November 2020 (UTC)
thread_title:  Fossil Range Error 

message: If ambulocetus belongs in the order, Artiodactyla, then this placement should be based on preserved limb morphology resembling hooves or other shared morphological features with other Eocene artiodactyla. The skeleton illustration provided does not appear show the evidence (at least to me) of hooves or other anatomical features found in other early artiodactyla. A topic in this article explaining the classification of the genus ambulocetus under Artiodactyla would clear up any confusion. Be sure to find primary sources discussing the reasoning behind the taxonomy of this species.Rigognos Molinarios (talk) 22:04, 30 March 2021 (UTC)

thread_title:  Hooves? 

message: "Ambulocetus probably had a long, broad, and powerful snout, and eyes near the top of the head."
I thought that the scull has been preserved sufficiently well to know such things without "probably". Hasn't it? Эйхер (talk) 08:31, 3 July 2021 (UTC)
replies: text: In the body of the article: "The snout was quite broad, but the end of the holotype's snout is missing, so it is unclear how long it would have been."  —PaleoNeonate – 11:48, 3 July 2021 (UTC)
