Hola

these woods are all from dicots.

It would be nice to have some more info about age and provenance

they look diffuse porous, thus rather from tropical to subtropical settings, but a complete view of the assemblage is necessary.

try to contact IAWA for a specialist of these woods.

Darwin:

You are advised to contact Director, Biral Sahni Institute of Palaeosciences, 53 University Road, Lucknow, India for expert identification.

Hi Darwin,

I agree with the previous comments. By narrowing down the possible taxa to the site based on modern vegetation communities would provide greater ability to identify to at least family or genus level, if lucky to species.

The identification process for wood requires, not only the transverse sections, as shown in your images, but also the tangential (for ray types, fibre pits etc) and radial (for ray composition, vessel-ray crossing pits etc) sections. By having all 3 sections described as per the anatomical features in Wheeler EA, Baas P, Gasson PE (eds) (1989) International Association of Wood Anatomists List of Microscopic features for Hardwood Identification, IAWA Bulletin 10(3):219-332, then use InsideWood (2004-onwards) http://insidewood.lib.ncsu.edu/search, to search and come up with possible matches. InsideWood 2000 menu has a fossil wood search option.

Image 1 & 2 has mainly solitary vessels with tyloses, vasicentric parenchyma & radial to diagonal vessel arrangement. These features are all very distinctive. As are the vessel arrangement and parenchyma bands in images 3 & 4. This will help narrow down the possibilities.

All the best.
