... to mind as I thought about Caroline Strömberg, this year’s Schuchert awardee. As you know, Caroline is a paleobotanist, and her primary study organisms are grasses. Grasses are a fantastically successful group, but they are mostly herbaceous plants, and from a paleobotanical point of view the most notable...

...Ethan G. Hyland; Nathan D. Sheldon; Selena Y. Smith; Caroline A.E.

... transformed the North American landscape from forested Eocene habitats to open Miocene grasslands (Graham 1999 ; Edwards et al. 2010 ; Strömberg 2011 ). Over this environmental transition, ungulates evolved higher crowned teeth and increased mean body mass as adaptive responses to these new niches (Alroy...

... also started to take shape during this period, and floral and faunal communities experienced a series of shifts toward the development of modern ecosystems; one of these key transitions was the evolution and expansion of C4 grasslands (e.g., Edwards et al., 2010; Strömberg, 2011; Herbert et al., 2016...
