Hi @jim-barkley. Could you add Phanerozoic Eon, Mesozoic Era, Cretaceous Period, Late Cretaceous Epoch to this specimen? And do you know the nearest town to where this was collected? Thanks!

Mack, Colorado, is the nearest town, but it is probably 25 or 30 miles away.

This is another example where we could use slightly more precise location data before marking as research grade. Either GPS coordinates or something like “25 miles north-northwest (I’m just making up the direction here) of Mack, CO” in the field notes should suffice. Thanks!

Beautiful specimen @jim-barkley! Any chance you know the nearest town to where this was collected?

I think the nearest town would be Delta, UT, but it would over 50 miles away. Lots of country between towns out there!

Certainly big county out there @jim-barkley! Is there any way you could use Google Maps to get GPS coordinates that more closely relate to the location? I’m just trying to think of ways to more accurately record location so that we can mark this as research grade. Thanks!

Hi @jim-barkley. Just wanted to clarify the location so we can ensure it’s accurate before marking this as research grade. It looks to me , based on the location of Antelope Springs, that the site would be 69 miles north, not west, of Delta. Is that correct?

@Sean Moran no, it is 69 mi west, north of US 50. You’ve been looking at google. Get a topo sheet, pg 35, loc A5, Utah Atlas and Gazetteer.

Hi @jim-barkley, any chance you know the nearest town to where this specimen would have been collected? Thanks!

Ilion, I think. So much like those from the Alan Lang Quarry, that I am making an educated guess that it came from the same vicinity. Purchased from “Extinctions” off ebay.

@mackenzie-smith and @indah-huegele any ideas on this one?

@vperez This was one I was working on last night/this morning. Still going through families.

Anonaceae, Winteraceae, Meliosma, Styloceras and Altingia is my running list so far.

Ericales also possible.

Ilex and Oleaceae. I’ll try to narrow it down from there.

Any update on this ID @mackenzie-smith?

@smoran and @jim-barkley I don’t know for sure but I’m ruling it down to Ericales. This is an order level ID. It includes plants like blueberries, kiwis, tea and Symplocos.

@smoran and @jim-barkley My reason for doing this was overall shape and some of the other hypothesized plants had extra loops before the margin.

@jim-barkley This might be a series of suggested taxa so there might be several posts. The lighter leaf (edges of picture) could be Winteraceae or Berberaceae.

MacKenzie I think the lighter one is Allophylus flexifolia. The darker one is the question mark. Also, I didn’t know how to handle two specimens on a single plate. The database is a little restrictive.

Hi @jim-barkley! I certainly see the overall shape and asymmetrical base as being similar to Allophylus. However, the secondary veins of Allophyllus are crasspidodromous meaning that they go directly to the margin. The veins on this leaf bifurcate before they get to the margin. There are also several intersecondaries which is something I don’t see…[Read more]

Thank-you, Mackenzie. I will re-shoot this and try again.

@mackenzie-smith were you able to narrow down the ID on this one?

@vperez and @jim-barkley I can’t see the venation on the dark one. It’s too dark. The overall shape looks Salix like (willow). Salix has been described from the GRF in 1934 by Brown. This image is just for the darker one. The lighter one has it’s own specimen number and image.

MacKenzie Smith I added some pics that show a little venation as well as a Salix that should illustrate the differences. Thanks for looking.

For this one, we can put class Actinopterygii and same updates to the geochronology.

Hi @jim-barkley ! For this one, we can update the taxonomy and say at least the class Cephalopoda and update the geochronology with the same info as the previous specimen.

Hi @jim-barkley ! If you update the taxonomy and the geochronology we can mark this as research grade. For taxonomy, we can at least say this is from the class Anthozoa. For the geochronology, Eon=Phanerozoic, Era=Paleozoic, Period=Carboniferous, Epoch=Pennsylvanian.
