Re: What did Spinosaurus eat? New species of Lepidotes found

OK, I'm a little confused here.  The oxygen isotope ratios for
_Spinosaurus_ indicate that the body was immersed much of the time.
Immersion in
water reduces aerial evaporation and therefore decreases enrichment of
18-oxygen in body water.  So I'm not sure how the heron analog fits
with this.
