Question

It is winter in Montreal and you are walking through a park covered in snow. Looking around, you see ‘trace fossils’ of human activity. Describe five ‘trace fossils’ that you see and assign them each to a behavioural category (the same used for trace fossils). Be creative.

Behavioural categories:

Feeding traces – Fodinichnia, trace fossils formed by deposit feeders as they excavate the sediment in search of food
Resting/hiding traces – Cubichnia, traces of organisms left on the surface of a soft sediment
Grazing burrows – Pascichnia, trace fossils of a distinctive kind indicating an animal grazing
Traces of locomotion – Repichnia, locomotory tracks that show evidence of organisms moving from one station to another, usually in a near-straight to slightly curved line
Dwelling traces – Domichnia, dwelling structures that reflect the life positions of organisms, for example the burrows or borings of suspension feeders
