Macrocrinus crinoid fossils from the USA

Crinoids are also known as sea lillies, a marine animal which fed by filtering small particles of food from the surrounding water.

Despite the 'sea lily' name, and sometimes the appearance, crinoids are not a form of plant.


Our current stock includes:

  • #1 - 76.4x41.3x21.8MM - Macrocrinus mundulus from the Lower Mississippian Muldraugh formation.
    It was found at Indian Creek, location 7, in Montgomery County, Indiana, USA. It has a horizontal crack running through some of the matrix of the specimen, but it is stable.
    The crinoid itself appears to be in very good condition, with a calyx, arms, and a stem visible - the arms are particularly detailed and look almost 'feathered'. Unfortunately one arm does have a small crack.


Frequently asked questions and delivery information

How do we grade stones?

There is no overall universal grading system for the majority of our products. As such, the grades we use are internal only. They simply refer to higher and lower qualities, but they may be entirely different grades to other websites. C grade pieces are of lower quality than B grade, which is lower than A grade.


How does our ordering and delivery process work?

You place an order via the website. When it’s been picked and packed, your order will be marked as completed and dropped off at our local post office. We have an account with the post office called a “Drop and Go” account, which allows the post office staff to process our parcels when they have free time, rather than me queuing up and delaying everyone else.

I get tracking information etc online when this has been completed. I typically do not send tracking information to customers unless they request it – but if you’ve requested tracked postage, it has been sent tracked! If you have any worries or concerns about your parcel being delayed please feel free to get in touch and I’ll send the tracking info over! We also get delivery confirmations for parcels over 25MM thick by default.


How do international orders work?

After Brexit, with the UK leaving the European Union, certain things have changed with regards to international orders. European Union customers will now likely be liable to pay the same amount of import VAT as any other international customers. You will be responsible for any customs and import fees.


I’d like to return my order for a refund.

No problem at all – just get in touch and we’ll arrange it. You can read our full returns policy here.


What payment methods do you accept?

I can accept Paypal, Stripe, cheque, and direct bank transfers. Paypal and Stripe will both allow you to pay with credit and debit cards.
