Hiya ,folks 
 don't know how I missed this one yesterday ,the rock is about 8-9ft tall and the fossil is about 6ft long , guess that it is a root or branch maybe.
plus 2 finds , is the 3 photo a fossil ?
Photos 4,5,6 from cocklawburn beach, went at high tide , ops ,but still a few for the camera 
last one from beadnell beach ,an orange coral lithostotian  Resized_20191023_210437_9566.jpeg  IMG_0134.jpg  IMG_0137.jpg  IMG_1954.jpg  IMG_1955.jpg  IMG_1956.jpg  IMG_0144.jpg

Hi Ratty,
I'd have to go for some kind of Actinocyathus for #3....TqB will know for sure.....
Looks like a very interesting beach.

All except the first photo are derived from older rocks, transported by ice to their current location.
Photo 2 contains a selection of Carboniferous brachiopods.  You have Productids (more globose, finely ribbed) and Spiriferids (broader and flatter with coarser ribs).  Someone here may care to offer more detail on the genera and species.
Photo 3 is a really delightful polished pebble of Carboniferous compound coral.   I used to call it Lithostrotion (considered to be the compound form of the one in your last photo) but there are experts to hand who will pronounce on what it should be called today.
Photos 4, 5 and 6 are, as I am sure you know, partly disaggregated crinoid (sea-lily) debris from the Carboniferous.

As for your first massive slab.  I agree, it looks rather plant-like...the small pimples still preserved in places remind me of "root hair scars" so I would suggest it is root of some quite substantial, probably Middle Jurassic plant, embedded in a ripple-marked sandstone.  I cannot find anything resembling it in the Palaeontological Association guide "The Jurassic Flora of Yorkshire", but that contains no root illustrations; only the parts growing above ground.

Along with Pete, I think that 3 is Actinocyathus, probably A. floriformis - it seems to have the large, bubbly dissepiments that the septa don't cross, so ruling out Lithostrotion. A finely coloured piece that would probably look great polished! 

The last one is now called Siphonodendron. Lithostrotion is restricted to the honeycomb species of the group (similar in colony form to no. 3).

The first one is basically a Stigmaria type root (all Carboniferous around here!).
