Subject:Just looking for some friendly advice
Posted by:blue_cat_23.
Time:10:20 am.
Hey guys!
I just wondered if I could get some input from any and all paleontologists/ people interested in paleo.  I have been wondering about something.  Right now I'm a senior Anthropology major and I'm not planning to change my major, however I'm super interested in not only getting my masters and phd in Physical anthro but also someday I hoped to do some paleontology work as well.  So I guess my question to anyone who might know is:

If I have my Ph.d. in Physical anthro and am working at a museum preparing exhibits bones etc.  (and assuming that in grad school I've taken some geology courses)
Would I be able to also work with dinosaur bones?  Do you have to have a geology degree to do any sort of paleontology work?  If I'm preparing human bones (which I already know quite a bit about), wouldn't it be the same methods to prepare non human bones? 

If anyone can help me out with any info I'd so much appreciate it!  :)))  
Like I said I don't plan to change my major so if the answers to these questions are no then I guess paleontology would be a good hobby to complement my anthropological studies.

Thanks in advance for any and all help,  AND your time!   :)

Subject:Australian Megafauna - Procoptodon and Diprotodon - fossils available
Posted by:tetsuan_atomo.
Time:12:57 am.

Hi Guys,

Just to let you know, I have some Australian Megafauna fossils I'd be happy to trade or sell to those with interest in the area.

I have 16 pieces of Procoptodon (giant kangaroo) bones of varying sizes, that I was allowed to keep after an expedition by the state museum.

I also have an enormous tooth, about a foot long and still showing its original enamel, and a couple of skull fragments from a Diprotodon (giant wombat) that I found myself on a geology field trip.

I have documentation authorising the export of these fossils outside Australia.

Not meaning to spam, its just that I'm aware this kind of material is very rarely available and I'd like to see the specimens go to an appreciative home ;]

I can be contacted at leary.joe@gmail.com for photos and further information

selling replica fossils. I have some great ones of T-Rex, and a few others for sale. Keep in mind, all are replicas. I do not handle or sell real fossils, as many are protected or to fragile to be handled.

If interested the site is http://www.storesonline.com/site/1552817

I joined this group, because I also enjoy learning about and discussing about different dinosaurs.

Time:11:34 am.
Heylo! XD Ah joined this community a while ago and have been a bit disappointed at it's lack of activity. ^__^ But I was doing random google searches this morning and found some cool news articles that I thought I would share. Hopefully get the community actives a bit and stuff.

I'm not really new to liking dinosaurs. XD But I am new to learning about them and their eras and stuff. So I can't engage in like super scientific debates yet or anything. ^.^;;;

New Dinosaur Found in Italy I think this one is pretty interesting because of it having the 'wishbone' like birds do and being a fairly large predator. o.o

Smallest Triceratops Skull This one is pretty cool too. o.o Especially the picture of the two skulls together. I'm glad that they have proff that the frill wasn't just for sexual displays now. XD Although I was unaware they thought it was before. I always thought it was away to intimidate larger predators by making it look bigger than it was, and wouldn't the placement make it harder for a predator to get a hold of the neck of the triceratop? >__> And the neck is a good place to go for, for an 'easy' kill that stops you from taking too much damage most of the time.

Those are it for now! XD I have some more articles to share but my connection is being crap and not letting me get them. ^__^

Subject:Jurassic Tyrannosaurid Discovered in China
Posted by:sangotaijiya.
Time:8:50 pm.

Scientists unearth the grandaddy of Tyrannosaurus rex
By Mark Henderson
A small, crested dinosaur that may be the ancestor of Tyrannosaurus rex has been discovered in China, scientists said yesterday.

Guanlong wucaii, the “crowned dragon of the five-coloured rocks”, lived in the late Jurassic period about 160 million years ago, making it the earliest known forerunner of the tyrannosaurs, which had been considered the oldest member of the dinosaur family.

The newly identified dinosaur was much smaller than its later relative, growing to about three metres (10ft) from head to tail. The largest known tyrannosaur specimens were significantly bigger, reaching up to 13m (42ft) in length. Guanlong wucaii, however, boasts several anatomical features that clearly mark it out as a primitive tyrannosauroid — the group that includes Tyrannosarus rex and other great predators of the later Cretaceous period, such as Giganotosaurus and Gorgosaurus. Tyrannosaurus lived between 85 million and 65 million years ago.

Two skeletons belonging to the creature, one almost intact, were unearthed by a team led by Xing Xu, one of the world’s most successful fossil hunters, of the Institute of Vertebrate Palaeontology and Paleoanthropology in Beijing. Details of the finds are published today in the journal Nature.

The discovery, in the Wucaiwan area of the Junggar Basin in the Xinjiang province, offers new insights into the evolution of the tyrannosauroids, fleshing out the “tyrant king’s” family tree.

It has the characteristic enlarged skull, powerful hind legs, stubby forelimbs and blade-like teeth of the group. Guanlong wucaii is also remarkable as it has a large, spectacular crest on its skull. The feature has surprised scientists, as it is highly fragile and would have been a considerable handicap to a predatory species.

Dr Xing said that the likeliest explanation for the crown was as an ornament used in sexual signalling. He likened it to the elaborate tail of peacocks.

First Jurassic dromaeosaurs and now a Jurassic tyrannosaur. *swoons*

Subject:Tyrannosaurus clux?
Posted by:sangotaijiya.
Time:12:55 pm.
For decades T. rex was thought to be descended from Allosaurus, a Jurassic carnosaur. Just about every book I read said that. T. rex inherited North America from its ancestor Allosaurus and continued the reign of terror.

Nowadays thanks to modern scientific techniques and new fossile finds we know that's not true. For one thing, T. rex's bones were found to be hollow, with the exception of the legs. Allosaurus' bones were solid throughout its body. For another, smaller members of the tyrannosaur family such as Daspletosaurus and Albertosaurus bear a striking resemblence to the raptors like Deinonychus.

Recently in Mongolia, the earliest ever known member of the tyrannosaur family was a found, a little guy that scientists named Dilong paradoxus, or Paradoxical Dragon Emperor. What made him so amazing was: he had FEATHERS!!! That's right folks, T. rex's great, great, great grandpa was a little feathered fellow (as I like to call those cute feathered dinosaurs they've been finding in Yixian, China recently). Having feathers means that Dragon Emperor was warmblooded and needed the feathers for insulation due to his small size. Dilong migrated west from China into Europe and North America, growing bigger as it went. It grew into Daspletosaurus, then Albertosaurus and finally T. rex.

T. rex adults didn't have feathers because they were too big to need them. The young however, would have. They were warmblooded, but would've frozen to death if they'd hatched with no covering, due to their being so tiny. So it's likely hatchling T. rexes had down till they grew to their juvenile stage and then would've shed them around that time.

Other ways T. rex was like a bird: Recently it was found that T. rex's breathing system was very similar to modern birds. Originally it was thought to be like a crocs, but this wasn't the case. How they can tell just from a skeleton is beyond me, but I guess they know what they're doing.

The most exciting thing though was the discovery of medullary (egg-laying) bone on the leg bone of T. rex skeleton that was recently found. For the first time scientists can tell the gender of the animal. The medullary bone is only found in female birds that are ready to lay eggs. Reptiles don't get this! So now they have found two distinctly avioid traits among tyrannosaurs: feathers and medullary bone. This is a very exciting time to be a dinosaur fan!

So when I think of T. rex, I'll end up thinking of Big Bird instead of Godzilla. XP

Subject:Massospondylus helpless at hatching
Posted by:sangotaijiya.
Time:11:36 am.
We know that many Cretaceous dinosaurs such as Maiasaura were attentive to their young. Many thought that the more primitive dinosaurs of the Triassic and early Jurassic were precocial at hatching, meaning able to leave the nest right away and look after themselves. The discovery of a baby massospondylus just about ready to hatch has changed all that.

The eggs were found over 20 years ago, but only with modern technology were the infants inside discovered. What was found, shocked scientists to their very core. These babies had cartiligenous bones when they hatched, meaning they couldn't walk right away. Also, they had no teeth! No precocial reptiles that hatches has no teeth! Even baby crocs, which are cared for to an extent by their mother, have teeth!

This means that baby massospondylus were altricial, meaning they had to stay in the nest for a time after hatching and needed food brought to them, pre-chewed by their parents. When the babies were able to walk, they walked on all fours instead of on their hind legs like their parents. This is interesting, because massospondylus is a prosauropod, which is the ancestral group of sauropods, large long-necked dinosaurs that walked on all fours. The massospondylus hatchlings seemed to be a precursor to what was coming.

Subject:T. rex, great hunter or lowly scavenger?
Posted by:sangotaijiya.
Time:11:20 am.
OK I'll get the ball rolling. Was Tyrannosaurus rex, one of the most popular dinosaurs ever, a great hunter like a lion, or a lowly scavenger like a hyena? For years, T. rex has been portrayed as a great lumbering hunter. Eventhough dinosaurs weren't supposed to be warmblooded, smart or fast, T. rex could still hunt because everyone else was just as slow and stupid.

In the last 20 years that thinking has changed dramatically. Dinos are no longer regarded as dimwitted and clumsy. No one's saying a Triceratops could outrun a horse, but lately some scientists particularly Jack Horner think T. rex couldn't hunt.

They say it couldn't hunt because of its small forearms, the "fact" that it couldn't run any faster than 20 MPH due to there not being enough muscle on its legs and the fact that it had a great sense of smell, which is akin to a scavenger.

First the thing about it not being able to run is based on the idea that it must've been eight tons or more. But recent studies have shown that all the bones in its body except the legs were hollow. If that's the case, that would reduce its body weight by half or more, thus enabling it to run.

The argument about the forelimbs is just weak. The secretary bird of Africa doesn't have hands with which to hunt. It just uses its feet and beak to pick off snakes. So what's everyone's take?
