My first thought was...(in your last photo), is two 'upright' Sealilly.. 'Criniod' flowertops/caps! Nice.

Hello adamlray, what I meant/see from your last pic is the 'closed cap' with sediment surrounding/embedding its tentacles.
Here's pics for comparsion of my only (very rare) complete plant, from roots to flower... with the 'cap' tentacles slightly open.

TJE, but look how deep the grooves are. Aren't plant impressions/ fossils usually very flat?

Good pics! I'd say 99% sure.."sea lilly"....depending on the age/formation of the stone they are in..it changes the look of all fossils, for example...the fossil of mine is 430-450 million yrs of age/ Silurian era. Yours may be younger..or older! Plus, being found in a creek bed there is water erosion to help expose your find! nice one!

The object does have a resemblance to a crinoid. Be advised that crinoids are not plants. They are filter-feeding animals related to starfish.

It does look similar to a crinoid, but it also reminds me of lepidodendron bark. Just a thought

Hey Age old, very nice! Do you the estimated date/age of your fossil? I've some I found from the eastern slopes of the Rockies 20-some yrs ago.
