We continue with the Cambrian.

Yeah, I'm familiar with smaller divisions. What I originally said was from the Cambrian through the Cretaceous we'd go by period, and from Cretaceous onward we'd go by Epoch, as those are the divisions in time that are most often referred to (for simplicity's sake).

 

Yeah, the Paleocene and maybe the Oligocene might be stumbling blocks but then we can also wait a couple of days until someone comes up with a Paleocene fossil.  I have a number of Paleocene and Oligocene fossils but I can't get the photos fast enough to contribute every day or two.  The other option would be going with Paleogene (Paleocene, Eocene, Oligocene) representatives in the absence of a quick Paleocene example with the Eocene as an easy go-to for many of us (numerous Eocene marine sites up and down the east coast of the US, around the Gulf Coast, and terrestrial sites from the Rocky Mountain states and Canada, and of course all the Eocene sites across Europe and north Africa - spots elsewhere too).

I can cover those two time periods on the days you don’t @siteseer 

[Ludwigia]

Eurypterus lacustris. Late Silurian, Pridoli, Bertie Group. From Ridgemount, Ontario.

 

[Kane]

The classic Odontocephalus aegeri of Pennsylvania, M. Devonian, Onondaga.

[fossilsonwheels]

Glikmanius occidentalis from the Carboniferous of Kansas.

Permian, the Permian,

so difficult the Permian... .

[fossilsonwheels]

A nice Permian Pleuracanthus tooth from the Tambach Formation of Germany. 

[Mochaccino]

Interesting thread! Hopefully I'm doing this right:

 

A Triassic fish nodule of Pteronisculus cicatrosus from Ambilobe, Madagascar

As long as you are posting a fossil, you are doing it right .

Nice fish, btw! Thanks for sharing!

I don’t have too many Ammonites.

 

 

[FranzBernhard]

Only barely scratching the fossil realm, just some Cretaceous microbialites:

And from the Paleocene this tooth of Otodus Obliquus.
Khouribga - Morocco.

Glossopteris must be one of my favourite fossils.

I have quite a few, and they are all different.

So don´t miss the Permian .

[Ludwigia]

Clavilithes noae from the Eocene Lutetian at Fleury la Rivière in the Paris Basin.

 

[Notidanodon]

Lepidocottus Amies from the chattian of eguilles

Scyliorhinus teeth from the Calvert Formation

Here's a juvenile Carcharodon carcharias tooth (Early Pliocene, Capistrano Fomation, Oceanside, San Diego County, California) with irregular serrations.

[siteseer]

Here's a Panthera atrox premolar in a jaw section (Late Pleistocene, tar seeps, Maricopa, Kern County, CA).  P. atrox has been called "the American lion" descending from P. spelaea, the European cave lion.  It's also been considered an extinct species of large jaguar.  Whatever it was, it's very rare where it occurs.

Yes, I didn't think of the Permian as a stumbling block but it can be.  You can find Early Permian terrestrial vertebrates from the southwest U.S. and Germany and some plants that age here and there.  It's tough to get Late Permian material.  Some ammonites have come out of Russia and Timor.

Now this is a nice fossil.

Nobody with something from the Precambrian.
  @Yoda perhaps.
