@jim-chandler Thanks

@gail-tennant, @jim-chandler  I’d say it is definitely bone and I don’t see any matrix on it.  You need to have someone put eyes on the specimen before you start removing anything that you think is matrix as it may be part of the fossil.

The specimen looks quite porous. Is it fairly light in weight or really heavy like a rock of the same s…[Read more]

I’m looking forward to the start of the Fall 2017 webinar series, “FOSSIL Roadshow,” scheduled for this Wednesday (Sept 20) at 7pm Eastern!  This time I get to participate in the series as a general attendee, instead of working behind-the-scenes. 😉  I believe the first episode will feature Dry Dredgers such as @jkallmeyer, trilobite expert Dr. B…[Read more]

Hello all,

The full-sized poster can also be downloaded by following the link: https://www.myfossil.org/lesson-plan-poster-using-fossils-to-determine-earths-past/

it has been posted under our Resources tab, K-12 Lessons as well!

@jim-chandler let us know what you think!

Hi @jim-chandler, because the poster was too big, @richard-bex used a workaround. Click the link at the end of his post. It should automatically start a download of the poster for you. As a low resolution “teaser”, I took a screenshot from my computer for you to check out. Is there anything in particular you’re interested in on the poster?

For those who may not know what we’re talking about, the Alf Museum of Paleontology in Southern California uploaded a great video on the International Day of Women and Girls in Science 2017 (this past Saturday, February 11).  The video featured paleontologist @taorminalepore, giving us a quick word on what it is like to be a woman in…[Read more]

Aw Jim, thank you so much for watching and for your kind feedback! I’m glad the talk was useful!

Gabe, aw man, you’re gonna make me all misty-eyed. I think it’s safe to say we inspire each other. I know that you inspire me every day!

Hi Jim @jim-chandler.  Thank you for your response.  It could be Dendostrea frons, but the ribs on the one I found originate at the hinge of the shell and from what I can see in the frons they originate more from a center line of the shell.  It does appear that there are remnants of possible clasper spines on bottom shell, but it is hard to sa…[Read more]

Excellent resource, @rnarducci!  Thank you for sharing.

@jim-chandler, @lmccall, @jon-cartier, @acurrier – did you see this?

@christine-verdi and @jim-chandler – Thank you very much for your comments about the Fall 2016 webinars!  I am glad that you enjoyed them and found many aspects useful.

@jayson-kowinsky, @bmacfadden, @dbutler, and @rnarducci – You all would probably appreciate reading Jim’s excellent feedback to each of your webinars.

@jim-chandler, you ask…[Read more]

@lance-comfort @lmccall@jim-chandler  Lance, I had to look that ID up on Google.  I’m an invertebrate guy.  After looking up Tilly Bone and the more technical term I was still unsure if this thing is some kind of normal fish part or a pathological one.  Anyway, a very interesting find.

@jkallmeyer@lmccall@jim-chandler  With your help I believe I have figured this one out.  I believe it is a fossil Tilly Bone (Hyperostosic Bone) from a large bony fish.  What do you think.  Here is a magnified picture from http://lakeneosho.org/Fossil/index.html, which looks very similar to mine.  Thanks….Lance

@jkallmeyer@lmccall@jim-chandler It is fossilized.  Does not Float.  Heavy, 96 grams.  Here are a couple more pics
