Hi I wondered if anyone knew what these were in the bedrock at Port Mulgrave? 😁

Hi

I am sure someone on here is more familiar with the rock features there than I am and can explain th geology of the place. You could do an online search yourself to see if you can find anything.
The last two pictures could be infilled burrows of some kind or just have a geological explanation.

Hello Zach and welcome to the forum. This is a burrow, infilled with mudstone, you haven't included a scale, but I would say a crusacean made it.

Hello, in " The jetrock series and the alum shale series of the Yorkshire coast" by M.K. Howarth (1962), are these features discribed as the " pseudo vertebrae" a series of concretions of unknown origine.
This publication is a must for those that wish to explore the geology of the Yorkshire coast, written by one of the greatest, but poorly known, brittish scientist of recent years.

greetings, Bert

Think Bert's got this one right - seen similar nodules at Port Mulgrave myself when I've  been down there.
