Re: fossil sponge...coral...or what?
Hi,
my impression is that it might be part of a decapod carapace. The colour and preservation suggest to me that it is not that old - say Holocene (recent) or Pleistocene (ice age) . Mr G++gle suggests that there are freshwater Pleistocene deposits in the Huntington area.

I was recently asked if I knew anyone who could give a zoom talk / demonstration for beginners about starting out in macropho...

hi,
i am not sure whether you have to join the group to access the files, but Steve Gill has made available to the yahoo diatom group a very comprehensive list of diatomite sites:

enjoy!

hi, it is nice when everyone is right ! bernhardinho is right they are trichomes....in this case 'trichosclereids', but tsavorite is right as well in that the rough granular texture of the trichomes is due to encrusting calcium oxalate crystals. See here for example: http://reviste.ubbcluj.ro/contri...

Hello René, a nice set of images and great dedication over a number of years. My impression is that they might be zygotes or auxospores of a pennate diatom. This could explain: 1. Why they do not look like any diatom you are familiar with 2. why the shape is very inflated 3. why the 'ornamentation' ...

Hello John, I agree 100% with Bernhardinho, these are fungal conidia.The group of fungi that produce them are known as 'aquatic hyphomycetes' - about 300 species are known. If you do an internet search you will see the range of unusual spores (conidia) that they produce. You should not be at all emb...

Hi, in reply to ChrisR, Charles has imaged (brilliantly as usual) a type III trichome (hair) which has five cells in the stalk. The pigmented cell contains and secretes flavonoids. See here: http://onlinelibrary.wiley.com/doi/10.1111/j.1756-1051.1990.tb02094.x/abstract Unfortunately, I do not have a...

Hello Michael, I think that the red stained areas are short glandular trichomes which would stick out from the surface and be pulled off with the peel. Although not very clear in your image, i think that you can see the arrangement of the cells in the base of the trichome. Compare perhaps with this ...

Michael, are you sure that the cells are actually present - could this be a cuticular peel or an acetate peel? My reason for thinking that this might be the case is that in your photos we see no 'side' cell walls and indeed no 'back' walls of the epidermal cells. If the epidermal cells were present,...
