What do you call the dishes that were used years ago to hold bones from chicken meat etc accumulated on dining table?

The dishes used to hold bones from chicken and other meats accumulated on the dining table were typically called bone dishes or bone plates.

They were often small, shallow dishes made of china or pottery, designed to be placed next to the dinner plate.

Here are some other terms that were used:

* Bone boat

* Bone bowl

* Waste dish

* Scrap dish

It's worth noting that these terms were used more commonly in the past, and are not as widely used today. Modern dining etiquette encourages discarding bones directly onto a plate or into a bowl for disposal, rather than using a separate dish.
