Shale is not a good building material, it’s too friable (crumbly). Slate starts off as the same rock ans shale except it undergoes a bunch of heat and pressure which makes it much less friable and an excellent material for things like roofing tiles and mantles.
That’s what the three shells are for.

iNaturalist is definitely a good suggestion, but it is NOT an assassin bug, wrong markings and body form. It looks to be in the genus Alysus. Here’s what iNaturalist gave me as a likely hit. Also, I’d recommend the Seek app (it’s associated with iNaturalist) over iNaturalist app for casual users as it gives quick likely identifications through real-time image matching and does not require engaging the broader iNaturalist community.

Australian coffee shops are the best.

My wife got sick as a dog after eating chocolate chip cookie dough. She spent a whole day going between bed and the bathroom. Strangely enough, she still eats raw cookie dough. Having gone through it with her, I don’t even like the fake/safe cookie dough in ice cream.
Looks like chicken mole. Hope to try it sometime (maybe at a more simple restaurant).
