Cretaceous Burmite: Evidence for a Remarkable Predator Prey Relationship
Biotalker posted a topic in General Fossil Discussion
An unusual type of beetle called Cascomastigus monstrabilis, of the subfamily Scydmaeninae or ant-like stone beetles, has a remarkable adaptation of their antennae. The eyelash looking structures called setae give the antennae the ability to serve as a trap to catch their prey, the tiny and numerous Collembola or springtails. The clublike maxilla palps may help to bring them to the beetles jaws. See this reference: https://www.nature.com/articles/s41598-017-00187-8.pdf?proof=thttps%3A%2F%2Fwww.nature.com%2Farticles%2Fsj.bdj.2014.353%3Fproof%3Dt Predator: Here are three Cascomastigus monstrabilis from my collection. They range from 6-9mm long. -
Myanmar Amber ([Unnamed Fm.], 99.34-98.10 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Coleoptera with exuded gas bubbles; these are likely methane, and could be the by-product of methanogenic bacteria inside a xylophagous (wood-eating) species. Some adult members of the Cetoniinae subfamily (family: Scarabaeidae) are xylophagous and known to produce methane; while this is known from Recent species, it's possible such characteristics could be found in extinct members of the Scarabaeidae or Scarabaeoidea (superfamily). This inclusion is contained in the same specimen depicting pholadid crypts. Provenance of specimen is Tanai Township, Myitkyina District, Myanmar. This image was captured using a HAYEAR HY-1070 microscope.© Kaegen Lau

Again an insect photographed in Naturistorisches Museum Wien (Vienna natural history museum), only indentified as "Coleoptera" in the tag. This one also comes from Liaoning, China. Notice the short antennae and strong granulation in elytra. By general shape this could be maybe a Buprestidae but it's very tentative. They also reminds me a bit the living Melyris (Melyridae). Size is about 12-15 mm lenght. Any help please? Thanks!
