Port Mulgrave is less than two miles south of Staithes and about three miles north of Kettleness. There is a steep path down the cliff giving access to the exposed rock platform when the tide is out. Don't get cut off by the tide!

This Ammonite (Eliganticeras elegans) is from the shales of the Upper Lias at Port Mulgrave and measures 3 inches along its longest axis. It shows parts of the original shell together with a layer of Iron Pyrites (the gold area) immediately under it.

A fossiliferous nodule from the Upper Lias at Port Mulgrave. Numerous ammonites and bivalves can be seen. The size is 4.75 inches across the widest point.

This Ammonite, (Dactylioceras commune), from the shales of the Upper Lias at Port Mulgrave, was found inside a nodule on the shore. Size is 2.5 inches in diameter. The remaining part of the nodule is also visible.

This ammonite covered slab of shale I picked up on the wave-cut platform, which is exposed at low tide, at Port Mulgrave.

These rocks are part of the Upper Lias (Jurassic) series and are, generally, very fossiliferous. These ammonites are probably Hypoceratids and could well be from the Jet Rock series as squashed Hypoceratids are abundant in that zone.
