Am I to believe that this was real?How can a land animal possibly achieve this size?

>>4466838>How can a land animal possibly achieve this size?By having better respiratory and skeletal systems than mammals.
>>4466852necessary but not sufficient
By laying eggs, so you're not limited by gestation time.Also having air sacs to make you lighter, like birds have today.
Here go you, faggot op.https://www.youtube.com/results?search_query=how+dinosaurs+big
>>4466863>Also having air sacs to make you lighter, like birds have today.u wot mate?Birds have less dense bone, more like a honeycomb structure, and it's not filled with air They don't have air sacs. Also that only works due to birds' size. Their bone mass isn't sufficient to support dinosaur sizes.
>>4466892I'm not angry at you, just disappointed.
>>4466892Birds have 4-12 extra lungs, generally called air sacs. These extra lungs or air sacs sit next to the neck, spine, chest, hips, legs, wings and tail. The bones they sit next to have tiny holes (foramina, c.f. pneumatic pleurocoels or pulmonary diverticulae) by which air enters the bones. The hollows of the bones are also lined with pulmonary tissue, effectively making the bones into lungs, allowing the bird to breathe through its skeleton. also birds don't inhale and exhale the same way mammals do, air flows in a loop constantly through their bones and lungs. finally they lack the diaphragm used by mammals to breathe, and instead pump air using movements of the legs and hips.these conditions are also found in saurischian dinosaurs, the theropods and sauropods.> Their bone mass isn't sufficient to support dinosaur sizescorrect. Sauropods shouldn't exist based on known biomechanics, just as bumblebees shouldn't fly. But they did, and nobody really knows how.
>>4466895isn't funny how if you mention something someone hasn't heard of, instead of saying "tell me more" or "where did you hear that?" they say "LOL UR A RETARDED LOL RETARD"
>>4466928I think he said>u wot mate?not exactly an insultyou are a retard though.
>>4466838Ask your mom.
>>4466904Maybe they were made of different materialshttps://youtu.be/9cVAVQih_pA
>>4466840>what you believe has no effect on realityWho's reality?
>>4466940Pretty good hypothesis>we find that adult sauropods sat in recliners all day>they asked their children to bring them tons of grass to eat every hour and change the channel on netflix for them>if the young sauropods refused, they slapped them and asked them if they wanted their parents to starve to death>a few mutterings of "after all I did for you" and "kids these days," the young sauropods would go back to cleaning house and serving their parentsreally it's the only model that works
>>4466944>Who's reality?truewho is reality?
>>4466928I think its justified as it was a response to >they dont have sacsif you dont know something dont make statements
>>4466928They guy typed out "birds don't have air sacks" which is embarrassingly incorrect.
>>4466981>if you dont know something dont make statements/an/ would literally disappear in a day
>>4466981>say something stupid>anons correct you>anons mock you for stupidity>leave the thread and pretend you never said stupid thing>next time someone says stupid thing you correct them>also mock them for not knowing thing>pretend like you've always know and were never stupid yourself>maybe even pretend you invented/discovered thing that anon doesn't know>lather>rinse>repeatwhen I first came here nobody knew about avian air sacs. Some of those ignorant fucks are probably itt educating people and acting all superior right now.
