From;  Author:Stand originally
People discovered not little dinosaurian and skeletal fossil, have female dinosaur among them for certain, also have male dinosaur, but what is female dinosaur, what is male dinosaur, this still is the problem of a not easy answer really. Somebody thinks, akin and individual dinosaur, of female somes what should compare male is big. But how to distinguish to fossil framework, still do not have a law to master really. Alligator kind be dinosaur be born now near, so the scholar finds out the distinction of both of male and female through anatomizing a few alligator. Result discovery, what arc of outspread the first arteries and veins is down to want to compare female alligator below vertebra of male alligator end is opposite want a few bigger, give an in part greatly almost. This is the genital because of male alligator -- phallic compressor is worn on the bone thorn that is born in arc of the first arteries and veins. Contrary, the arc of the first arteries and veins of female alligator grows some smallier, outside needing to be born without phallic compressor besides female alligator, likelihood and female alligator should lay eggs about, arc of the first arteries and veins is some more smallish, when egg yields, won't get block up. Investigator checks dragon of Xiang Yu the Conqueror and bald dragon with this kind of method, still discovered the circumstance that arc of the first arteries and veins follows sexual distinction and changes really. Had we found the way of appraisal dinosaur sexual distinction? Still need to undertake checking to more dinosaurian fossil, just can make affirmation or negative reply.
