Brachiosaurus is estimate to have weighedclose to thirty metric tons . Put two of these heavyweight together , and you ’re dealing with upwards of 125,000 pounds of dinosaur .
Now , attempt to imagine all 125,000 of those pounds organize for the sake of copulation , and you ’ll set out to prize how baffling the mating auto-mechanic of sauropod dinosaur ( the most colossal animal to ever live on land ) truly are .
Over on Dinosaur Tracking , Brian Switek has write two posts ( in an on-going , four - part serial publication ) examining how , on the nose , these dinosaur might have done the deed — and it is an outstanding read . Included here is an excerpt from the first installment , but you ’ll definitely want tocheck out both office in their entirety .
In 1991 , the American Museum of Natural History reveal one of the most fantastic dodo displays ever make . Placed at the center of the renovated Theodore Roosevelt Rotunda , an adult Barosaurus rears back to protect its offspring from an oncoming Allosaurus . The defending sauropod dinosaur ’s head is 50 substructure up in the zephyr , although whether or not such an immense , long - neck dinosaur could have pulled off such a exploit has been a continuing pointedness of tilt . Even in a distinctive military capability , Barosaurus must have had a powerful centre to pump rakehell along its 25 - understructure neck , and who know how intemperate the dinosaur ’s essence would have to work to continue bloodflow to the animal ’s forefront if it reared up ? Some paleontologist weigh such a feat physically inconceivable , but as paleontologist William Gallagher pointed out while teaching my Paleontology 101 stratum at Rutgers University , male Barosaurus had a upright grounds to rear up . How else would the huge dinosaurs have position themselves to mate ?
Exactly how dinosaurs got it onhas inspired no modest amount of surmise . The large dinosaur of all , the sauropod , have been especially puzzling . We often say that these dinosaur “ shook the earth ” with their footsteps , but did they also make the layer rock with their love life ? ( I rationalize for that jest , and will keep the geology puns to a lower limit . Promise . ) Paleontologist Beverly Halstead famously wondered about dinosaur sexuality in public talk and articles , and he suggested that stock “ dinosaur fashion ” was for a male person to get along alongside the female and throw its stage over the female person ’s back as she rise her posterior into the tune to move her tail out of the room . In the case of sauropod dinosaur such as Diplodocus , Halstead even suppose that the amorous dinosaur might intertwine their tails . While other fossilist have considered the buns - twist panorama unbelievable - sauropod dinosaur tails were balancing organs and were too strong to closely coil around each other - the basic dinosaur office Halstead promoted has remained a salient possibility for the dinosaur kama sutra .
But not everyone harmonize that giants such as Apatosaurus and Brachiosaurus were up to of such nupital acrobatics . These beast were so immense - Apatosaurus , not even the largest sauropod , is figure to have weigh more than 23 tons - that some researchers thought the kind of status Halstead was push would give the dinosaur fractured legs and broken in spines . At a symposium of vertebrate morphologists held at the University of Chicago in 1994 , life scientist Stuart Landry , Jr. gave a short presentation ennoble “ Love ’s Labors Lost : union in Large dinosaur . ” He did not see how sauropod could have tangle on land . A declamatory , rearing sauropod , he say his audience , “ would have to digest 10 to 20 tons in a precarious position two or three meters off the background . ” A male Apatosaurus would be liable to bung over and possible take the female person with him . alternatively , Landry suggested that the bombastic dinosaurs looked for muholes or bodies of weewee to buoy themselves up . When a conference meeter asked if he was nominate that all dinosaur couple in water , Landry respond , “ I would say the very large single must have . ” Of course , this speculation require a large number of Jurassic and Cretaceous spicy tubs of just the right astuteness for sauropod dinosaur to multiply , and scientific models of sauropod dinosaur have suggested that these dinosaurs were actually quite buoyant and unsound in H2O . Sauropods were diverse , disparate and widespread brute that roamed in terrestrial habitats all over the world - there ’s no reason to presume that the largest dinosaurs had to attempt out the approximate deep lake when they catch the itch .
you’re able to see to it out the remainder of the sauropod sex series — which will be continuing through Valentine ’s 24-hour interval — over onDinosaur Tracking .
