Plan a trip →Visit the Molermuseet on Mors first. The museum runs guided digs in adjacent quarries during summer. Coastal exposures along the Limfjord can be searched at low water.
Quarry digs through Molermuseet (paid). Coastal foreshore is open with normal Danish 'allemansretten'-style access norms.
Danish heritage law: significant vertebrate fossils belong to the State (Danekrae rule) and must be reported. Hobby material is yours.
- Slick mo-clay (slippery)
- Cold North Sea wind
- Quarry equipment if visiting active sites
- Book the Molermuseet's organized dig — best legal access and you keep what you find (within Danekrae rules)
- Mo-clay splits along bedding planes — use a thin chisel and split rather than chip
- The Limfjord ferries connect Mors and Fur cheaply
