The truth of rings?
I wonder if the growth rings appearing in dinosaur bones ("Growth Spurt: Teenage tyrannosaurs packed on the pounds" SN: 8/14/04, p. 99) are analogous to those of trees, which are determined by the annual climatic cycle. Is it possible that the dinosaur rings were created on a different time cycle? JAMES HENDRY, FLORISSANT Florissant (flôr`ĭsənt, flŏ`–), city (1990 pop. 51,206), St. Louis co., E Mo., a suburb of St. Louis, on the Missouri River; inc. 1829. There is light manufacturing and limestone quarrying. The city was settled by French farmers and fur trappers c., MO.
Researchers say that they haven't come up with another type of cycle that seems feasible.--S. PERKINS
