In terms of iconic dinosaurs, the gargantuan sauropods are certainly up there. Along with the mostly meat eating-theropods, and herbivorous and often armoured ornithischians, they form one of the three major groups, or clades, of dinosaurs, and were the biggest animals to ever walk this Earth.
The end of the Jurassic period, some 145 million years ago, was a pretty important time for sauropods. Their diversity was already in decline through some of the latter part of the Jurassic, but it seems that they were hit pretty badly at the Jurassic/Cretaceous (J/K) boundary, in an extinction event that may have been quite severe among land and marine-dwelling animals.
Seed dispersal by animals is incredibly important for plants to help them occupy new areas of land and reproduce. Usually, this happens using bugs, birds, or intrepid kittens, but probably the last animal on this planet you’d expect to disperse seeds is crocodiles – you know, those big beasties that take down bison for a snack. Well, turns out, they do, and it’s a process known as saurochory.
Not only that, but these king archosaurs, the vintage cousins of dinosaurs, the ones who you never smile at, eat fruit to get at seeds. A new study reviewed the diets of modern crocodiles, and showed that 13 of 18 species ate fruit of some sort (frugivory), along with a wide variety of plants.
