We post a lot about the Carboniferous swamp plant fossils - and for good reason, as these are incredibly important to both human history and science in Northern England!

These swamps were also home to a range of other creatures, including lots of fish and sharks...

Tiny fossil cogs?
Not quite, these are single segments (ossicles) of a crinoid stem.
In life, soft tissues would have run through the central hole. The radial groves and ridges would have prevented the sections of the stem from twisting in currents.

Some fossils leave an impression on you - or on the rock!

We spotted this impression of a spiriferid brachiopod on our way up Pen-y-ghent over summer. If you look carefully you can also see a crinoid ossicle.

We're hoping for the rain to stop so we can get back out into the hills!

Even in poor visibility on top of Ingleborough, we still found fossil plants!

This is in the Millstone Grit at the very topmost part of the peak.

Today's #FossilFriday post is a Sea Monster and some Seashells...

Why? Because tomorrow afternoon we are back at the fantastic Land of Iron Museum to take people on a tour of the Jurassic ocean!

Some fossils really stand out from the rock.

We spotted this vibrant solitary coral in the Yoredale series of rocks near Pateley Bridge.

This trilobite has a very cute name - Dindymene - at less than 1cm across it's more like Diddymene!

At 440 million years old this fossil is from some of the oldest rocks in the Yorkshire Dales, and appears to have been slightly distorted over the years...

Picture in your mind a shark tooth... We bet this isnt the shape you were thinking of!

The shark Ptychodus had a 'pavement' of these strange teeth for crushing hard-shelled prey. Ptychodus fossils have been found all over the world, including from Hessle near Hull.

For #YorkshireDay and #FossiFriday we're celebrating the giant ammonites of Yorkshire!

From the foreshores of Redcar with their monstrous Arietites, to the oolite of Malton with its mighty Perisphinctes - and beyond!

Lurking at the bottom of the limestone in the dales is a rather impressive conglomerate – a rock made up of pebbles of other rocks.
This piece was pulled out of a cave by divers and contains a few
gastropods in amongst the pebbles – can you spot them?

With Lancaster Dino Fest just around the corner, we're highlighting fossils from Lancashire!

Much of Lancashire is underlain by Carboniferous rocks, this lovely fern was found in one of the many coal mines from the area.

Digging a railway in N England in the 1800s usually resulted in finding huge fossil trees!

These pair of Sigillaria were unearthed in 1837 in the outskirts of Manchester.

On July 12th we're exploring the fossil trees of the NW at Lancaster Dino Fest, come along to find out more!

With this hot weather it seems appropriate to post about the tropical inhabitants of the Jurassic Seas of Yorkshire.

This little chlamys (a scallop) was found in a stream near Kirkbymoorside, although during the Jurassic it would have been a shallow tropical sea.

Heading to Redcar tomorrow for the Fossil Walks with the Yorkshire Fossils Festival team?

Before you head down to the beach, cast your eyes to the pavements. The promenade along the front is paved with some incredible Carboniferous fossils in black limestone.

This lovely fossil is a sapling of a giant plant similar to those in Bradford's parks. It's photographed upside down to clearly show the 4 branching roots that all of these plants have - unfortunately the one closest has broken off and is missing.

Some creatures are windows into the past - others are just windows...

This fossil is a fenestrate bryozoan. The fenestrate part of the name derives from the Latin for window, and refers to the grid-like skeleton of these filter-feeding colonial organisms.

The spectacular main chamber of Gaping Gill is one of the largest underground chambers in Britain.

There are a few fossils which can be seen in the limestone of the caves, including this magnificent fossil coral near the waterfall that was pointed out to us by an experienced caver.

Heading out to a park this #FossilFriday?

Be sure to visit Horton Park in Bradford, where you can see one of three huge fossil trees!

These Carboniferous giants were excavated from Clayton in the late 19th Century and placed on public display to "inspire future generations of geologists".

Looks like we're in for more glorious weather here in Yorkshire!
With extremely low water levels it's a great time to head out to a stream to see what you can find!

We recently spotted this lovely little Siphonodendron amongst the cobbles in a dry stream near Horton in Ribblesdale.

Some beds are so distinctive we can use them to work out where we are in the sequence. One such bed is the Clayton Shell Bed.
Found in the Harrogate area this shell bed contains a wealth of marine species including these beautiful spiriferid brachiopods.
