Cretaceous of Brazil (Crato Formation) The environmental setting is semi-arid, at the shores of a lagoon. A mayfly (Coxoplectoptera) rests on a shoot of a flowering plant. One of the flowers is being pollinated by a wasp, Cretosphex parvus (hymenoptera: Sphecidae). The reconstruction of this plant is based on a fossil of an unidentified angiosperm, possibly related to magnolia. At bottom left is an arachnid - camel spider (solifugae) - about to eat a cricket which was itself in the middle of eating a plant (a Crato monocotyledon plant - Kitzschophyllites flabellate. These plants branched into threes (trifurcated) and had single leaves on each branch with serrated margins). At lower right are two antlions (Baisopardus cryptohymen) showing distinctive wing margins. I have painted one with wings 'open' and the other 'closed' showing how the wing patterns differ when they overlap in 'closed' position. You can just make out two water-striders on the water. Behind, a small raptor (Santanaraptor) looks out across the lagoon while two pterosaurs (Lacusovagus magnifens) wheel overhead. The reed-like plants are quillworts (Isoetes). Ferns are Ruffordia. There are also some water lilies near the santaraptor; they are too far away for any anatomical details.
