Hi, I'm trying to id a fossil but since my area of expertise is not about insects I'd to know if somebody can orient in my search for the affinity of the following two mandibulate capsule-like structures. I looked at several images of similar structures and I decided that they could be chironomid head capsules, but... I don't know how to upload the images. can somebody let me know, please?
