Fossil Insects from the Eocene Florissant Fossil Beds (Teller Co, Colorado)
Opabinia Blues posted a topic in General Fossil Discussion
Being a Colorado native, I have taken multiple trips to the public-access Florissant Fossil Quarry located near Florissant Fossil Beds National Monument in Florissant, Teller County, Colorado. This quarry provides fossil collectors fantastic access to the shale layers of the Florissant Formation, a late Eocene (Priabonian, ~34 million years old give or take) lagerstatte known for its diverse fauna of fossil insects, in addition to plants, gastropods, and very rarely vertebrates. Most fossils occur in very thinly laminated ashy grey shales. Other lithologies present include well-sorted tan cour- 8 replies

Cretaceous Burmite Dipteran stuck in amber just after Eclosion
Biotalker posted a topic in General Fossil Discussion
This dipteran became stuck in amber approximately 100mya just after eclosing (coming out from its pupal case as a new adult). The shape of the wing indicates it was in the process of unfurling and therefore never took flight. -
Burmite Cretaceous Soft Tissue: Remarkable preservation of Dipteran Indirect Flight Muscles
Biotalker posted a topic in General Fossil Discussion
Here is a Cretaceous Burmite Midge that appears to show preservation of the indirect flight muscles in one hemithorax. Indirect flight muscles distort the thorax cuticle from the inside to indirectly move the insect’s wings and power flight. While this level of microscopy cannot prove the tissue is muscle, it seems likely that the two sets of power muscles for flight are visible in this fossil: six dorsolongitudinal muscles (DLM) and six dorsoventral muscles (DVM). There are smaller muscles that play a role in guidance and directional movement that may be present but cannot be unambiguously d- 11 replies

Taxonomy according to fossilworks.org. Diagnosis according to Sawabi et al., 2018 p. 7: “Small to medium slender flies; body length 1–9 mm; most species with greenish to blue metallic luster, while others dull yellow, brown or black in color. Eyes large and prominent. Antennae aristate. Ocellar bristles and outer vertical bristles well developed in most species. Legs long and slender. Wings clear or patterned with darker areas towards the wing margin; wing venation reduced; three radial veins R1, R2 + 3, R4 + 5 present; posterior basal cell and discoidal cell always fused; anal cell alway

[ Baltic Amber Inclusion ] Diptera In Copula - Mating Flies - Rare Action Scene :)
vermiculosis posted a topic in Micro-paleontology
Dear Friends, This time i'd like to show "scene" from Baltic Amber. Diptera In Coupla - Mating Flies - Copulating Flies. Very good quality for scene like this. Collectors love inclusions like this. Sometimes i got flies in "mating position" but they are not "connected" on 100%. Very clear amber also with ant inside and other flies but i cant upload more mb Enjoy ! Cheers From Europe Artur -
[ Inclusion Inside Baltic Amber ]Rhagionidae - Blood Sucking Snipe Fly. Perfect Specimen.
vermiculosis posted a topic in Micro-paleontology
Dear Friends, This time i'd like to show wonderful Snipe Fly, Blood Sucking Fly ( Rhagionidae ) from Eocene age. So perfect after that 40-54 million years. Closeup macro shot i made from 30 stacking photos. I hope in future i can get equipment for making 200-500 shots for focus stacking This fly is not super rare in Baltic amber but in that condition it is ( for that family ). Enjoy Artur -
