Hi, Robert.
Robert Byers writes: Observe with ALL attention without preconceived ideas.In fact i suggest one observe on youtube the marsupial wolf and see all the likeness to a regular dog. Moving or still pictures. Right. So, like I just said, you advocate looking at vague, overall "likeness" and ignoring in-depth detail. Or, as I shall now rephrase it, you advocate watching YouTube videos instead of running cladistic analyses with codified characters. -----
Robert Byers writes: The appearance of a creature is due to profound anatomical structures. And, "profound anatomical structures" are due to assemblages of smaller parts. A pile of pebbles can look a lot like a pile of beans. But, relatedness is more than just similarity of the overall "pile": it's similarity of the parts from which the overall pile is generated. Thylacine parts are essentially marsupial parts assembled into a dog-like pile. -Bluejay (a.k.a. Mantis, Thylacosmilus) Darwin loves you.

Robert Byers writes: In fact i wrote a essay called "Post flood Marsupial Migration explained" by Robert Byers. Just google.I know my issue. ... The like traits are so alike they MUST invoke convergent evolution to explain them. The few traits in common deal with minor points of reproduction. A few other minor details of the brain, teeth, etc. Yet to see this defining the marsupials into a group means to ignore the fantastic number of traits that would simply put them into regular groups of creatures. I read your essay Robert, with some difficulty. You seem to insinuate in it, and in your posts on this thread, that the marsupials in Australia are all just minor modifications of some 'kinds' of ‘similar shaped’ placental mammals. But I note you seem to focus your comments on marsupials with the most similar traits to extant placental mammals (eg marsupial moles, thylacine, etc). Just for laughs I'd be interested to know what 'kinds' of placental mammals you think that kangaroos, platypus, possums, wombats and koalas all belong with. Edited by Boof, : Change subtitle

Hi, Boof.
Boof writes: Just for laughs I'd be interested to know what 'kinds' of placental mammals you think that kangaroos, platypus, possums, wombats and koalas all belong with. They're all their own "kinds" of placental mammals, of course. For some inane reason, Robert has decided that letting marsupials be related to one another would be admitting the veracity of evolution, while having them be related instead to similar placental mammals would not. And, by the way, platypus aren't marsupials; they're monotremes. -Bluejay (a.k.a. Mantis, Thylacosmilus) Darwin loves you.

Did you watch the moving marsupial wolf?
I say its just a wolf with a few minor details of difference. The same details of all the creatures in the area. There are marsupial lions, moles, rats, tapirs, bears and so on. To have something look like something else requires fantastic conformity of thousands of twists and turns of anatomy. The classification system has simply been incompetent and likewise for many orders of creatures in the fossil record.

The creatures that are alike tell the tale. anyways the creatures in australia would just be the same with creatures everywhere filling the post flood planet at that time. tHe fossil record is full of creatures that have gone extinct all over the planet since the biblical flood by this creationist reckoning. Australia is a window into the whole world at that time.

robert, can you please propose a marsupial thread, where you elaborate on your position regarding the relationship between placental and marsupial mammals?

Hi Robert,
This isn't the right thread for a discussion on marsupials. Could you boil down your web article on marsupials into a thread proposal over at Proposed New Topics? Thanks! Edited by Admin, : is => isn't

My apologies to the Mods & posters but I wanted to spare you all the initial problems and frustrations I had when chasing up defunct links.
Arachnophilia kindly linked to an article by Greg Paul on Feduccia's bird-digit paper (Message 64). This was hosted originally on the Dinosauria on-line website which is now dewfunct. However all is not lost. This paper and the rest of the useful articles on the old Dinosauria pages can still be found at the Wayback Machine which is hosted on the Internet Archive (Internet Archive: Digital Library of Free & Borrowable Books, Movies, Music & Wayback Machine). Dinosauria.com can be found here : Wayback Machine1/http://www.dinosauria.com/ And Paul's original comments can be found here : Wayback Machine1/http://www.dinosauria.com/jdp/archie/paulfed.html I leave it to the Mods to decide where this info can best serve the forums users. Regards to all. Edited by MiguelG, : No reason given.

I have several nice pictures of the Thermopolis Archaeopteryx specimen. I took them when it was displayed at the Houston Museum of Natural Science.
I also have a really good reproduction of the Berlin Archaeopteryx specimen.

it saddens me to know that dinosauria went down.

This looks like the right thread for this information I stumbled upon.
