I’d like to identify as much of this as possible, any help would be appreciated. It was found at a site reported to be mahantango formation. It was found as float.February 6, 2017 at 9:21 pm #18634Jack KallmeyerModerator
@hunter-thurmond I would need a much closer shot of this to figure out what it is on. Can you do that?February 7, 2017 at 10:04 am #18661Eleanor GardnerModerator
As we saw before, @jayson-kowinsky is familiar with this formation, so he may be able to help you with ID.February 7, 2017 at 4:23 pm #18664Jayson KowinskyParticipant
This is a cluster of poorly preserved spiriferid brachiopods. They are found in clusters on occasion.
As to what type (genus) they are, I have no clue. There are lots of types and these ones are too worn to see any of the genus specific traits.
I attached a picture tracing them out on your image, and also an image of a similar cluster of better preserved ones from a different local.
The other side of it, it looks like that could be a piece of brachiopod impression (the ridges area). The rest of it may have a bryozoan colony growing on it, those tiny little bumpy thingys (to be technical).

@jkallmeyer I can’t get my iphone to focus much closer than that. The only other option is a series of shots through a 20x hand loop at different focus depths. I am in the process of acquiring a better camera so in the future I will have better shots. For now here is some of the side which might be a bryozoan.

@hunter-thurmond With those views it brings two things to mind: A encrusting coral or a stromatoporoid. It may take someone familiar with your area to be definitive on this after seeing the specimen in person. I have attached a close-up photo of an encrusting coral from here. It has more preserved detail but it does have a similar shape.February 12, 2017 at 4:12 pm #18682Jayson KowinskyParticipant
I’m still going to say it’s a Bryozoan colony encrusting the bottom part of your spiriferid fossils.February 15, 2017 at 7:48 am #18703Lisa LundgrenKeymaster
@hunter-thurmond if you’re looking for an inexpensive option to take close up shots of fossils with your iPhone, I can’t recommend the mPow lens kits enough. They are very affordable, and clip onto your phone camera lens. I know that some folks take issue with the fact that it can “bend” the image, but it does a pretty job good for the price tag.

@tmorgan might have a suggestion as she uses an interesting set up/attachment on her smartphone, if I remember correctly. @dellingson also uses iPhone lens attachments, and took some fantastic photos of fossils using his set up during a field trip in Nebraska, so he might want to chime in, too.
