Early Jurassic fossil plants from sedimentary rocks of Tabbowa, Sri Lanka show a variety of evidence for plant-insect interactions indicative of a terrestrial habitat prevailed in the Gondwanaland. The observed interactions are skelitonizing, blotch and galls, ovipositions or coprolites, leaf mines and leaf chewing. These traces indicate that insects had associated the plants for various purpos...
From well preserved leaf damage of the mid-Cretaceous Dakota Flora (97 million years ago), three distinctive, insect-mediated feeding traces have been identified and assigned to two extant genera and one subfamily. These taxa are the leaf miners Stigmella and Ectoedemia of the Nepticulidae and Phyllocnistinae of the Gracillariidae. These fossils indicate that within 25 million years of early an...
The spectacular fossil plant assemblage preserved in the non-marine Mount Flora Formation of northern Antarctic Peninsula represents diverse Jurassic flora that once covered Gondwanan continents at high paleolatitudes. depositional facies formation plays a key role tectonic interpretations and basin evolution models attempt to reconcile large igneous province magmatism, continental break up, ma...
