Estimating deep-time species-level diversification processes remains challenging. Both the
fossil record and molecular phylogenies allow the estimation of speciation and extinction …

Sharks occupy marine habitats ranging from shallow, inshore environments to pelagic, and
deepwaters, and thus provide a model system for testing how gross habitat differences have …

Understanding heterogeneity in species richness between closely related clades is a key
research question in ecology and evolutionary biology. Multiple hypotheses have been …

Sharks are iconic predators in today's oceans, yet their modern diversity has ancient origins.
In particular, present hypotheses suggest that a combination of mass extinction, global …

Environmental controls of species diversity represent a central research focus in
evolutionary biology. In the marine realm, sharks are widely distributed, occupying mainly …

Klug, S. & Kriwet, J.(2010). Timing of deep‐sea adaptation in dogfish sharks: insights from a
supertree of extinct and extant taxa.—Zoologica Scripta, 39, 331–342. Dogfish sharks …

Sharks (Selachimorpha) are iconic marine predators that have survived multiple mass
extinctions over geologic time. Their prolific fossil record is represented mainly by isolated …

Cladodontomorph sharks are Palaeozoic stem chondrichthyans thought to go extinct at the
end-Permian mass extinction. This extinction preceded the diversification of euselachians …

Summary The Cretaceous–Palaeogene (K–Pg) mass extinction profoundly altered
vertebrate ecosystems and prompted the radiation of many extant clades [1, 2]. Sharks …

Shark populations have been decimated in recent decades because of overfishing and
other anthropogenic stressors; however, the long-term impacts of such changes in marine …
