The impacts of relational organizing for health system and community collaboration: Early evidence from a rapid multisite qualitative study.

Objective: To understand the ways relational organizing practices impacted collaborations between independent or health system-affiliated community health clinics, public health offices, and community groups during the early COVID-19 pandemic.

Data Sources And Study Setting: Between November 2020 and June 2021, we interviewed clinical and public health workers, clinic-based community organizers, and staff and volunteers at community organizations who participated in three COVID-19 response collaborations in the Northwestern United States.

Study Design: This was a qualitative study employing participatory and rapid data collection and analysis methods.

Relict duck-billed dinosaurs survived into the last age of the dinosaurs in subantarctic Chile.

In the dusk of the Mesozoic, advanced duck-billed dinosaurs (Hadrosauridae) were so successful that they likely outcompeted other herbivores, contributing to declines in dinosaur diversity. From Laurasia, hadrosaurids dispersed widely, colonizing Africa, South America, and, allegedly, Antarctica. Here, we present the first species of a duck-billed dinosaur from a subantarctic region, , of early Maastrichtian age in Magallanes, Chile.

Bizarre tail weaponry in a transitional ankylosaur from subantarctic Chile.

Armoured dinosaurs are well known for their evolution of specialized tail weapons-paired tail spikes in stegosaurs and heavy tail clubs in advanced ankylosaurs. Armoured dinosaurs from southern Gondwana are rare and enigmatic, but probably include the earliest branches of Ankylosauria. Here we describe a mostly complete, semi-articulated skeleton of a small (approximately 2 m) armoured dinosaur from the late Cretaceous period of Magallanes in southernmost Chile, a region that is biogeographically related to West Antarctica.
