I have tried without confidence on my IDs for these finds from Sweetwater County, Wyoming. I suspect Sycamore?? It would be great to get these labeled properly!!!!

As long as I am at it, here is a picture. Not sure if it is wood splinters or needles or nothings. Opinions welcomed!!! Size is about 3-4 cm long.

Way to go. You have been hunting far and wide , Mike and finding high quality fossils.  Is'nt life grand?  As you know, little of this survives in my area, just fossilized wood and sometimes plant roots. High quality photos of high quality leaf surfaces (I love number 3). That last photo seems like twigs,  I will be watching with interest. :popcorn:

This looks like Paleocene flora.  The large platanoid leaves are Macginitiea sp. and the leafy shoots appear to be Glyptostrobus europaeus.

Thank you very much @piranha. The article was helpful and the IDs are great!! Any idea on picture 5?? I found multiple specimens and they all looked similar. Also the word platanoid used in your response is hard to understand. No definition can be found. I am just curious of its meaning.

Image 5 is: Equisetum sp. (Manchester 2014)

 

Equisetum is sometimes present, represented by stems and/or rhizomes and sometimes by rhizome nodules but detailed comparative studies with other fossil and extant species have not been done. Brown (1962) cited various epithets that had been applied earlier for specimens from the Rocky Mountains and Great Plains region, but did not settle on an appropriate bionomial, noting that “When, however, these species are examined in the light of the material now on hand, they do not seem to be readily distinguishable. Size of stem, number of teeth in the sheaths, shape of the tubers—all vary so greatly, with gradations from one to another, and with no apparent constancy in any set of features, that I shall not attempt to define the species” (Brown 1962, p. 46).

'oid' = suffix denoting shape, form, bearing resemblance: 'platanoid' = a member of the Platanaceae family.
