A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. 

It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya.

And the reverse side of the block is also covered with Dictyonema.

And also from the Oslo area, a slightly later Arenig piece featuring Tetragraptus serra.

Unfortunately, you can't see all four stipes on any of them. About 475 mya.

The reverse side of this specimen contains a completely different species of graptolite. (see next post.)

Nice specimens, we don't see enough graptolites. Dictyonema flabelliforme  is now Rhabdinopleura flabelliformis - I collected a few decades ago and only recently realised it had changed. :)

Thanks 

i'm way out of touch 

These were also collected twenty five plus years ago.

Here is the reverse side of that Tetragraptus piece above. 

This is Phyllograptus angustifolius also from the Huk Formation, Slemmested, Oslo Basin, Norway, roughly 475 mya. 

There are other graptolites visible, too, probably bits of Tetragraptus and / or other dichograptids I presume.

The length of the most complete one there is exactly 15 mm

Lovely Phyllograptus, it's been on my "to find" list for a long time.

Thank you. :)

It's the favourite of my graptolites and having the Tetragraptus on the reverse is a real bonus.

Labelled as Trilacinoceras hunanense, I reckon it's actually Lituites lituus. It's just listed as Ordovician but probably from the Pagoda Farm Baota Foration, Middle Ordovician.

I have  Lituites lituus and does look very much like yours. You do have some lovely fossils. 

 

Cheers Bobby

This is Ampyx pristus from the Upper Fezouata Formation of Ouled Slimane, near Zagora, Morocco, so Arenig, Lower Ordovician about 475 million years old or so. It's very nice, but I bought it and think the rostral area has been tampered with, in other specimens I have seen the rostral spine or horn at the front is molded into the glabella as if an extension of it , but here it is just a point at the anterior of the pre-glabella area. 

Anyway, here it is  :20171028_142316-1.thumb.jpg.92ce457058fffa5e35df0e3551bcd197.jpg

The correct species is Ampyx priscus Thoral 1935.  Unfortunately, the spines are all fabricated.
