Data from: Decoding the dynamics of dental distributions: insights from shark demography and dispersal

Sora Kim, Justin Yeakel, Juergen Kriwet, Meghan Balk, Jaelyn Eberle, Sarah Zeichner & Dina Fieman
Shark teeth are the most abundant vertebrate fossil, and because tooth size generally correlates with body size, their accumulations document the size structure of populations. Understanding how ecological and environmental processes influence size structure, and how this extends to influence these dental distributions, may offer a window into the ecological and environmental dynamics of past and present shark populations. Here we examine the dental distributions of sand tigers, including extant Carcharias taurus and extinct Striatolamia...

Data from: Probing the ecology and climate of the Eocene Southern Ocean with sand tiger sharks Striatolamia macrota

Sora Kim, Sarah Zeichner, Albert Colman, Howie Scher, Jürgen Kriwet & Thomas Mörs
During the Eocene, the Earth climate system transitioned from greenhouse to icehouse conditions. Central to many explanations is the Southern Ocean—where tectonic configurations influenced oceanic gateways, ocean circulation reduced heat transport, and/or greenhouse gas declines prompted glaciation. To date, few studies have explored the implications of this climate transition on high latitude, marine vertebrates. Seymour Island near the Antarctic Peninsula preserves a rich, diverse fossil assemblage in the Tertiary Eocene La Meseta (TELM) Formation (Fm)....
