Other than dinosaurs, Paleantology reminds me of Ross from Friends.

The long names put me off for a start. Call me shallow.
T Rex picked a brilliant name but it was their music that interested me, not the dinosaur but I've always thought that boys were/are particularly fascinated by diggers and dinosaurs. I was only there for a few days but met a man who's brother in law plays in T Rex. Perhaps the "the dinosaur island" inspired their name because it certainly was different. Sorry to take your thread so o/t Keyser but it's your fault for waking up my dormant mind for which I thank you. I'd say I'll read your links but I know I wouldn't absorb it all. |

Thanks for the kind comments folks.

A couple of discussions on just how large sauropods may have got.
http://svpow.com/2009/10/13/how-big-...d-trackmakers/ http://svpow.com/2010/02/19/how-big-...i-mean-really/ If you have an interest in these remarkable behemoths this site is just superb. ![]() http://svpow.com/ |

An article on a new book featuring the superb artwork of Julius T. Csotonyi - one of the very best illustrators of prehistoric life on the planet.

News of a new massive new Titanosaurid sauropod that has been discovered in Argentina.
At an estimated length of around 40 metres it is certainly one of the largest ever found but I will wait for the final calculations to see how it compares with the other supergiants. But it may well be the largest dinosaur for which we have significant skeletal remains (rather than extrapolations from fragmentary material) as there are seven individuals in this wonderful find. Sauropod weights are being revised all the time - downward - due to the tremendous lightening of the skeleton combined with their avian air-sac system and more accurate computer models. A few decades ago such an animal would have been thought to weigh more than 200 tons! There will undoubtedly be more articles on this beast over the next few days. Sod all you creationists - try fitting some of these buggers on the Ark. ![]() Enjoy folks. ![]() http://www.bbc.co.uk/news/science-environment-27441156 |

I was slightly ashamed yesterday when talking to a group of 3 years old that they know more about dinosaurs than me... So I'm coming to hide out in here for a bit to educate myself.

Abit more on the gigantic sauropod discovered recently.
![]() This femur looks even larger than the previous one (perhaps a bigger specimen out of the seven individuals discovered). ![]() http://metrouk2.files.wordpress.com/...op=1#038;h=478 Personally I think the estimated weight for this dinosaur (77 tons) is far too light, Argentinosaurus huinculensis has been estimated to weigh 73, 83 and 90 tons respectively in various recent publications. If Puertasaurus reuili has been estimated to weigh between 88-110 tons - see my previous post on this thread - then surely this massive beast could exceed 100 tons as well. It is all very interesting. ![]() https://au.news.yahoo.com/a/23616497...ur-discovered/ http://www.telegraph.co.uk/news/worl...Argentina.html http://www.newvision.co.ug/news/6557...argentina.html |

This is all strange. We are always told that gravity prevents animals/us growing over a certain size, and all of a sudden there is an animal the size of 20 elephants. God has probably put a big bone in the ground to see what we would do.

Bone is more than strong enough to support far larger dinosaurs even than these. Mammals seem to be constrained by inferior skeletal and physiological engineering (our lungs are far less efficient for example than the avian air-sac system of birds and dinosaurs) and their method of reproduction. But no one is quite certain why land mammals have never really got much larger than elephants IIRC.

Absolutely fascinating.
![]() Can you tell me keyser, that despite the fact these massive dinosaurs are longer than the blue whale, does the blue whale 'outdo' them in the sense of its enormous bulk weight? |

So it does at the moment, but ichnotaxa (footprints) suggest some may have exceeded the maximum weight of the blue whale (around 200 tons). http://svpow.com/2009/10/13/how-big-...d-trackmakers/ Although the remains have been lost Amphicoelias fragillimus could have approached or exceeded the mass of a large blue whale (the discussion at the end of both articles is excellent). http://svpow.com/2010/02/19/how-big-...i-mean-really/ Who knows what we will find in the future?

The largest dinosaurs from skeletal remains are all around 75 -100 tons.

I think we are so privileged to have this beautiful mammal in our existence. And so happy, that their numbers, albeit slowly, are increasing. |

I totally agree. ![]() Yes and no sauropods have quite beaten it yet, so for the moment it is the heaviest animal which had ever existed.

I agree! Thanks Keyser but where are the fish in the family tree? Or am I being thick?

It is interesting to note that the living Coelacanth species are actually far more closely related to us than they are to say a cod or herring.

A couple of pictures of the famous Argentinosaurus huinculensis skeleton.
http://upload.wikimedia.org/wikipedi...s_DSC_2943.jpg http://www.geek.com/wp-content/uploa...us-590x330.jpg Note however this is an extrapolation from a few bones - the new dinosaur is known from far more complete remains. Which is really wonderful news. ![]() Here are two different reconstructions showing the bones that have been found of Argentinosaurus. http://fc07.deviantart.net/fs71/i/20...ng-d30tysl.jpg http://fc03.deviantart.net/fs70/i/20...st-d5xy6n4.jpg |

Two slightly different perspectives on the gigantic Titanosaur discovery that has been in the news this week.
http://paleoking.blogspot.co.at/2014...saur-just.html http://svpow.com/2014/05/19/the-new-...gentinosaurus/ The discussion and debate of just how large this animal really was will no doubt continue until the paper is finally published.
