ABSTRACT. Vertebrate fossils from many different formations¯uoresce when exposed to ultraviolet (UV) light. In this paper ®eld observations and controlled experiments in the Chadron Formation (White River Group, late Eocene) of Wyoming are used to assess the utility of searching for fossils at night using ultraviolet light. The results indicate that, especially for very small teeth and egg-shell fragments, searching with ultraviolet light at night can result in signi®cantly more specimens than searching during daylight hours. This method has the potential to increase sample sizes for small vertebrate specimens that are often overlooked when using standard collecting techniques.

This curated list of resources collates interventions that effectively deploy education technology in settings of fragility, conflict and violence (FCV). The World Bank (2020) states that by 2030 FCV settings will be home to up to two thirds of the world’s extreme poor; these settings have become increasingly complex over the past decade, with the COVID-19 pandemic threatening to exacerbate existing challenges. This list explores effective uses of EdTech in FCV settings. It particularly emphasises interventions and evidence relevant to the Yemeni context and distance learning during the  COVID-19 crisis. These resources were selected with the intention to include practical recommendations on technology-enabled interventions which could support a proposed national distance learning system in Yemen.
