Whitby finds

[dhiggi]

Found these among other things in the Whitby area today. Everything we’ve found before today has been marine material from the Jurassic. Are they plant material or is such a thing not found here?

We only kept the first specimen as the other was large and crumbly. 

 Thank you for looking

My daughter spotted this massive pyrite ammonite on the shale bed too, we cleaned it up for a picture but left it for others to enjoy. Is it Phylloceras heterophyllum ?

Also found this ammonite, not much to go on yet but can anyone identify it by the spines on the outer whorls?

Only ever found one like it before at Whitby

You're right about the Phylloceras - wonderful things, and they get even bigger. 

 

Yes, they're plants, from the Whitby Plant Bed of the Saltwick Formation, Middle Jurassic (above the Lias). I'll probably get them wrong if I try to ID them - there are many types which look frustratingly similar unless you're familiar with them. Try Nilsonia and Zamites for starters...

 

The last ammonite looks like a Peronoceras. (Again, not my strong suit.  )

Thank you @TqB

The Phylloceras was based on one of your previous IDs. It was a beautiful specimen, shame there was no easy way to save it from inevitable destruction by the sea.

 

As for the plants; nice to have something new in the collection, even if is isn’t the best of examples. I’m now on the lookout for a second bookcase as her collection has outgrown the one.

 

Thank you, I’ll look it up

I agree with Tarquin that the last ammonite is probably a Peroniceras.
