At a site in Argentina, the remains of seven individuals of a new herbivorous dinosaur have been discovered. What makes this finding even more significant is that the species may have weighed 80 tons – the weight of 14 African elephants – and grown up to 40 meters long – the size of two semi trucks. This would give the species the record for the world’s largest dinosaur. The species does not have a name yet, but lived during the Mesozoic era, and much more of the excavation site is left to be discovered. Bones from the legs, neck, back and tail have been unearthed, and are complete enough that scientists think they have good precision for their size estimates.

I'm a plant biology PhD student studying monarch butterflies in Michigan, but I'm interested in lots of other types of science, too. I am interested in how breeding monarch butterflies choose their habitat based on floral species richness and abundance. Few studies have been conducted on optimal foraging theory when it involves an organism searching for two different kinds of resources, and butterflies are an ideal study system to investigate this, since many species are ovipositing specialists and only lay eggs on one species of hostplant, but are feeding generalists and nectar from a broad variety of flowering forbs.
