Speaking of Trey, i want to know what do you guys think of this video.

I think he's right this time, and there really shouldn't be much debate about this anymore with all that evidence.

yeh half and half rex is best rex
I don't care what the nerds say; these old designs were mint.
went fossil collecting today
found some nicely sized fragments of an Isotelus maximus shell
feels good man

Any good paleo books worth taking a look at? I need something to read at work and we can only read educational things

I mined some Olenellus clarki recently. Mostly found cephalons, but they were endless in those shale layers. Found one that must have been 3" across.
>>2084771
That's pretty cool, any more pics? Sadly where I grew up the rocks were all Ordovician, not my ideal age but I still found lots of little trilobites, and once even a crinoid that was in pretty good shape.
I live in BC now however, I'm dying to go to Yoho and maybe visit Walcott's quarry.
>It's a Trias/Jura/Creta thread
You all know this is basically the ass end of all the epochs right?
Which one is the best AT WHAT?
>>2085330
Yeah, first pic wasn't mine though. Wish it was, but finding full bodies was extremely hard. I'd give it a 1 in 1000 chance.
Pic related was the average good piece.
>>2085361
Above average ones were mostly found in green shale layers that were higher up in the stratum. Red shale like the first one didn't preserve finer structures well.
>>2085363
Little babbies weren't as common as I expected. I liked finding these.
>>2085364
And biggest one I found by far. Had no clue Olenellus species got this big. I bumped up the sharpness on this picture to outline it better.
>>2085365
Those were all early Cambrian trilobites.
This one I bought off ebay. Favorite trilobite I have. Flexicalymene retrorsa from Mt. Orab in Ohio. Ordovician. Don't know why, but they get preserved in an enrolled state frequently.
>>2085367

I've just find that and I can't stop laughing.
Fucking Tsintaosaurus.
It was a complete dickhead.

Kaprosuchus (Boar Crocodile)
There's something hardwired inside of us to find Crocodilians terrifying.
Now imagine one that's just as if not more formidable on Land as it is in water.

Looks like you could open it with a nutcracker and eat the delicious goo inside.

>>2086507
Oh fuck, I had all of those as a kid except the dragon and red thing. I remember that fucking abs monster.
>>2086511
I saw it at a store yesterday and saw it was called "realistic dinosaur playset" and had a dragon in it. And I thought to myself /an/ would love this
I sometimes like the old designs because they made the creatures look very lizard-like, not a lot of the current feathered dragon looking fellas. I like both for certain reasons.
>>2083714
JP dinos were all mutants, and probably should have looked more african frog-like.
Also I'm glad the Chaos Effect toy line got a moment in the movie after all these years.
How inaccurate is this baryonyx model?
>>2086667
fuck I want one
>>2085339
Does anyone remember those books from kindergarten and shit full of these prehistoric ecosystems? They had illustrations that looked just like this but i cant find them anymore, would love to buy them now
>>2083714
Do any of you know of any serious, scholarly sorts of books on prehistoric animals?
Whenever I look for something it always seems to just be kiddy/picture book shit, and that really bothers me.
>tfw you will never get to see what all those odd looking prehistoric animals looked like in the flesh
>>2086568
>Also I'm glad the Chaos Effect toy line got a moment in the movie after all these years
Yeah man, I remember having one of those toys and wondering "is this what the next movie is going to revolve around"? Kind of a shame they didn't do more with the theme.
Any of you niggers have any fossils? I've got a couple Trilobites and a rock with the remains of some 20 million year old herring in it.
>>2086968
hadosaur egg

mosasaur jaw fragment
and a few pieces of Lepidodendron bark I found on a exit pile of the old village mine on the beach
>>2086968
I've got a shitload of ammonite fragments and impressions, a couple bits of what i assume to be wood, a bivalve shell and a trilobite, but the latter was bought.
I'm actually planning on going to west runton tomorrow to see if I can find anything.
Would it have been possible that same species of Dinosaurs (T-Rex, for example), would have subspecies with both feathers and no feathers, depending on the climate it lived it. Kinda like elephants and mammoth?
>>2087030
yes, it's possible.
it's just extremely unlikely. That much allopatric evolution would almost certainly make them different species rather than subspecies. Possibly different genera even.
>>2087021
Man, I'd love to spend a day in the sun digging in the dirt for fossils..

It's England anon, no sun allowed.

You're what's wrong with the world.
>>2086667
Yeah I've seen that one, looks pretty great, but I'd personally prefer if it didn't have movable parts.
>>2086964
There are plenty. Check out Alberta University's MOOCs if you want someone simpler first, then read "Dinosaur Paleobiology" by Steven Brusatte and "Dinosaurs: A Concise Natural History". If you want actual science, you might want to google what the "science of prehistoric animals" is called. If you search for paleontology resources instead of just "dinosaurs", you're gonna find proper books. It's also really good to keep up with newly published papers, because there's new information every month.
You probably won't be able to find a good book on ALL prehistoric animals because there's so many and they're so different, there's no reason to squish them all into a single book. What are you most interested in? Cambrian invertebrates, dinosaurs, synapsids, mammals?
>>2086968
I got some trilobites, a fish, some extinct bison metacarpals, molars and vertebrea, part of a mammoth femur and something I've been told is part of a neck vertebrea of a diplodocus by the person who gave it to me.
I should probably try and find out if it really is.
>>2089270
fucking hell i'm full retard today
Amonites not trilobites
I also got a piece of rock I suspect is a piece of fosilized tree.

I dislike him to say the least.
>>2089333
he's not particularly well educated and spends hours saying something that can be said in five sentences.
>>2089333
I don't know why people get so worked up about the dinosaurs of Jurassic Park not being scientifically accurate
They explain it very clearly in the book that don't give a shit about that;they just wanted crowd pleasers
Currently doing the last assignment of my undergraduate degree. It's very broad paleozoology. For some reason I thought I'd look at Proboscideans because I thought there'd be a tonne of literature on it and they're all goofy looking fucks. NOPE.jpg.
Anyone know if theres a difference between tetrabeledon and stegotetrabelodon?
Searching suggests tetrabeledon was a gomphothere and that stegotetrabelodon was a genus, but also that stegodon was a genus.
>>2090422
"Tetrabelodon" is the same thing as Gomphotherium. It doesn't exist, it's just a junior synonym for the other.
Stegotetrabelodon and Stegodon are valid genera, and they are different from Gomphotherium ("Tetrabelodon").
Most of the original osteologies on these animals are going to be brief mentions in journals from the 1880's. A lot of that literature isn't available online.
I probably have the original "Tetrabelodon" work in my Cope library, but fuck if I know where.
>>2090422
Ignore me, did some digging and apparently someone put the gomphothere Stegotetrabeledon syrticus in to the Stegodon genus and that got circulated.
>>2090428
Ah thank you. Enjoy this weird platybelodon scaling edit that I found on flickr as a thank you.

>>2086964
Not my field, but you should look up which introductory books are used in university level palaeontology, then get those books, read them, look up the literature they refer to, read that literature, and so on.
>>2086964
I love the books of Alan Turner and Mauricio Anton.
So fucking awesome
>>2089087
>What are you most interested in? Cambrian invertebrates, dinosaurs, synapsids, mammals?
Well, at the moment, sea life invertebrates/vertebrates in general as well as post Cretaceous extinction event animals, generally mammals.
>>2089087

Jesus Christ, why is this so expensive?
>>2091919
it's a college textbook.
colleges can force you to buy textbooks, so the price automatically quadruples.
>>2091919
Because it's not a novel. Many people work hard together to publish such high quality scientific literature. Any good science book is gonna cost you. There are some torrents online though, if you can find them and there are Uni Alberta's MOOCs which are FREE and up to date.
>>2091917
>>2091153
Evolving Eden is pretty neat. I've heard good things about "The Walking Whales: From Land to Water in Eight Million Years" but I haven't read it myself yet. Considering you posted an Ambulocetus it might interest you. I don't know about any good book specializing in post kt extinction mammals, but I'd be very interested in it if someone knows of something. Maybe National Geographic Prehistoric Mammals?
I've just read "Dogs" and "Cats" illustrated by Mauricio Anton.
"Synapsida" by John McLoughlin is good if you're into that.

>>2093006
If I knew what species that was I could give some more points
>Pronated Wrists (the hands should be facing inwards, not down)
>No killing claw in the middle toe (pic related)
There's also a lack of feathers on the arms
Other than that it's pretty good
>>2093079
Forgot pic
>>2093079
>Pronated Wrists (the hands should be facing inwards, not down)
last month we were hunting down the Carpenter paper that everyone cites as evidence that they can't pronate the wrist.
I have it on my computer.
funny thing is he specifically says in that paper that Deinonychus CAN pronate the wrist.
if you'd like to know more where the myth got started I can tell you, I spent a couple days hunting it down on the interbutts.
>>2093086
If you've got evidence I'll look at it
>>2093079
I wasn't going for any species in particular, just kind of drawing whatever
Thanks for the input anon
>>2093157
Sure.
If you look into the subject you'll find everyone is citing Carpenter's paper, "Forelimb Biomechanics of Nonavian Theropod Dinosaurs" as proof that theropods couldn't pronate the wrist.
they particularly claim that raptors couldn't pronate the wrist.
The only raptor Carpenter studied is Deinonychus, and he specifically says in the text that it could pronate the wrist.
One example is here in pic related.
Last page of the study. Notice how Carpenter illustrates the wrist of Deinonychus exactly the same as anon did in his drawing up there. (example C). Read the description of the figure for one example of Carpenter discussing how Deinonychus DID pronate the wrist.....
>>2093477
>Folding of the arms DOES allow a form of pronation of the manus that only involves the wrist...
emphasis added
>>2093157
So anyways, basically what happened is Carpenter writes this paper saying that raptors could pronate the wrist but didn't normally walk around that way.
this is true of humans as well, we can pronate our wrists but we don't normally walk around with them pronated.
So this idea, "they didn't USUALLY pronate their wrists"
evolved over time into "they didn't EVER pronate their wrists,"
and then eventually into "they COULDN'T pronate their wrists."
of course that's not what Carpenter said at all. He said they didn't do it all the time, not that they couldn't.
>>2093006
Very nice.
>>2093498
it wouldn't seem to since feathers can be moved independently of each other in the direction opposite the overlap.
so it might prevent supination of the wrist but shouldn't interfere with pronation.

Carnotaurus
>>2089333
True tho
Tbh I don't think the frog DNA theory was debunked til many years after the movie came out either
For its time it was a fairly accurate movie
>>2086507
one of those is a mammal lol
>>2089333
Don't watch EWW.
It's a terrible YouTube channel regardless.
so what was the biggest sauropod?
>>2093822
Argentinosaurus I thought
>>2093822
What was biggest theropod?
So which species has survived the past 800,000 years mostly unchanged?
>>2094033
shark of your choice
>>2093777
As of the last couple years, I find the Ambulocetus particularly interesting. I mean come on... A Mammalian sort of crocodile? Pretty cool.
I'm really now decided to go for Paleontology in College, but there's no university here in my country that offers it. Is there even a university here in SEA that offers it? It could save me the trouble of studying in States
>>2093947
Spinosaurus I think.
>>2093777
I want to hug his tiny arms
>later die
I haven't been following dinosaurs for some years. (Just casually though, not like I'm a biologist) Now that some time has passed, are there people taking feathered dinosaurs too far? Are dinosaurs=birds as videos/articles indicate? I'm confused on the current state.
>>2093777
Best sausage. [spoiler]Nice trips.[/spoiler]
>>2083975
I saw a cool Carnotaurus (I think) in the same configuration, but I completely forgot how to find it. I wish to see more in fiction. Theres nothing wrong with taking older designs as passing them off as fictitious beings, right?
>>2095418
>Are dinosaurs=birds as videos/articles indicate?
birds are dinosaurs but not all dinosaurs are birds.
>>2095418
Not sure if this is 100% accurate or not so take it with a grain of salt.

It sure as hell took them long enough.
Inostrancevia, It was a gorgonopsid wich lived during the permian period.
>>2097899
I'd like there to be more love of the permian-triassic reptiles. My favorite being vancleavea. A 3-foot, long-necked, blunt-faced crocodile sounds so "exotic" and different, and not much effort has been done to study equally unique reptiles of this time.
>>2086530
Quetzzzzz
>>2097959
>not much effort has been done to study equally unique reptiles of this time.
the effort and the study is at least as good as with dinosaurs.
there isn't much effort to present those finds to the public is all. Just because there's a lack of strong interest.
I think you might be shocked by how little actual science is published about any famous dinosaur. Most dinosaurs get a single, 2-3 page paper, one entire page of which is just citations. Even extremely well-known and beloved animals like T. rex, you could fit every bit of science ever published about it in a couple books that wouldn't take more than a day to read.
Published science is generally very brief, and contains little if any of the things the public loves to read and discuss.
