Love the site, as a amateur collector of fossils I like how your site is presented. I just got back from visting Yellowstone National Park, and made the pilgrimage to Kemmerer, Wyoming as well. I had done a lot of research before I went on the trip to Wyoming, and found out about the fossil fish quarries in Wyoming. I wanted to make it to Utah to dig for trilobites as well but didn't have time. Hailing from Oklahoma City ,I was astounded that I have world class trilobites in my backyard. Do you have any detailed information about the let me quote you "A well-known location for collecting Devonian trilobites is called "White Mound", Haragan Fm., Hunton Group, near Sulpher, Oklahoma in Arbuckle Mtns.This is a private ranch and a fee area owned by Pat and Merylyn Howe.  At the time of my visit, there was a $25 fee to visit, plus $5 per person....." by the way "Sulpher" is spelled Sulphur on all Oklahoma state maps....Are there any other dig sites available for fees around the Arbuckle Mountain area? Does the White Mound have a website or Email or a point of contact? Thanks for your help in advance!

Reply: You're the second person this month to ask for more information on White Mound, so I guess I need to add it to the article.  Not sure why I didn't in the first place.  It's great that they let collectors like us collect on their land.  Here's the info I have from my Mar '03 trip:
    {contact info provided again, see next message}
I didn't visit any other fee quarries in Oklahoma, but I know Bob Carroll runs Black Cat Mountain Trilobites, but don't have any info on it.  You might try searching Google for "trilobites Oklahoma quarry fee" or for "trilobites Bob Carroll".  Happy Collecting!

My name is Louis Herzner,  I am in the Army and stationed in Lewisville, Texas as a Recruiter.  One of the high school kids that just joined told me
about finding fossils up in Oklahoma.  I started doing some research and found out about White Mound and then got your e-mail address.  I was hoping you would give me a call so I can take my family out looking.  Thank You so much!

Reply: I would recommend going to one of the private sites where they allow fee-collecting.  You will definitely find fossils which is a big plus when taking family.  From my experience, you especially want your children to come home with real fossils to spark their interest and motivate them for future outings.  Oklahoma has GREAT trilobites and brachiopods.  I went to White Mound which would be good.

My name is Andrew Taylor and I enjoyed your web site very much as I am very interested in Paleobotany.  I am going to Douglas Pass, CO, July 5 and 6, 2003 to collect fossil plants with the Western Interior Paleontology Society and I would like to know if there are any areas around Bonanza, UT that are open to collecting or any one I could contact in this regard.  Also I would be very interested in purchasing a copy of the Atlas of Fossil Plants when it becomes available.  If you could give me any information regarding collecting I would greatly appreciate it.

Reply: Regarding Bonanza, UT, there are several localities there that are on BLM land (open to collecting Ė as long as you donít sell them).  Iím reluctant to give the precise locations of the quarries in Bonanza though because DMNS is doing a lot of work there to collect specimens for the Atlas.  Iíve forwarded your request to DMNS to be on the waiting list for the Atlas (and Iíll keep your name too).  Michael Graham is very knowledgeable in the Green River Formation, Parachute Creek Member (which is Douglas Pass & Bonanza).  He has a BLM permit to collect in this area and also knows what is common vs. rare.  The best suggestion I have is to talk with Michael on collecting at Bonanza.  Maybe he could organize another trip or make it part of the Douglas Pass trip.  In any case, heís the guy to talk to and I canít recommend going to Bonanza without someone like him.

This is a great site.  I teach GED students, and I think this information will fascinate them.  It will bring history alive!

Reply: Susan,  Thank you for your kind comments.  I'm glad you found my site interesting and I'm really glad that you are showing it to your students too.  Education is my #1 goal with this site.  I'm working on a new section that you might also find useful Ė ďWhy Study Fossil Plants?ĒÖ  It will describe how scientists use the size, shape, and structure of leaves to estimate past climates (temperature & rainfall).  For example, the results from the fossil rainforest in Castle Rock, Colorado tell us that Colorado was much warmer and wetter 64.1 million years ago.  And, the geographic area has stayed pretty much at the same latitude as it is today (only turning somewhat).  So, we know that the entire planet must have been much warmer then too.  In fact, the equator was probably a very inhospitable place with very high temperatures.  Thanks again.

Hello,  I am  a Westminster student in Atlanta Georgia. I am doing a research project on the tuatara.  I was wondering if you knew anything interesting about it.  First, I was wondering if you knew it's scientific name.  Second, I was wondering when, who discovered it.  I was also wondering how big it can get and how small it can be.

Thank you for your time, Carly

Hi Steve,

[Comments regarding "Fossil Plants from the Denver Basin, D1 Section".]
Actually, Woodmen Road is an El Paso County road and, therefore, Chopping at the Gap is in El Paso County DOT right-of-way, not CDOT ROW.  CDOT provided most of the money for the construction project and that's why we are involved.  Nice-looking page.

Hi there,
I like your site.   I love geology and I live in castle rock so this is really interesting to me.  I wondered if you or someone would be able to let me know if the castle rock area has ever had any volcanic history, I was just curious because ryholite is so abundant here.  any way again I love the site.

Thanks,
Greg
Greg &/or Kellie Meyer  / GEM STAR Enterprises, Inc.

Reply: Greg,  Thanks for your comments on my site.  You are correct about the ryholite.  The Castle Rock area was devastated by a volcanic event in its past which actually originated up near Mt Princeton (by Buena Vista).  This occurred about 36.7 million years ago.  The eruption was a particularly violent type which produced "glowing avalanches" where the volcanic material covers vast areas very fast.  An image of this eruption was painted as part of the Ancient Denvers paintings at the Denver Museum of Nature & Science (DMNS).
You can see it at: http://www.dmns.org/ad/explode.html

The rhyolite has been mined in the past and it was used as building material for some of the old buildings in downtown Denver.  I think some of it was even used at Coors Field.  I learned a lot of this from a Geology course which is part of the DMNS paleontology certification program.  There's some discussion and images on the eruption and Castle Rock's history at the following links:

Thanks for the quick reply.  I went to all those websites.  I think I'm gonna try and find some more info on this Mt. Princeton eruption and do a project to present to my geology teacher, you may know him I know he goes up to DMNS often, it is Mr. Caldwell.  Anyway thanks again for the info and I will pass this info on to my class.

As a novice, I'm completely fascinated with all of the history around Colorado Springs. Thanks to a tip from Jon Thorson who has been patiently answering my questions, I found your website and am enjoying it thoroughly.

My wife and I have come across a number of 'rocks' lying about at the base of Pulpit Rock that are loaded with wood-plant-carbon particles. I'm attaching a couple pictures taken there.

Thanks for sharing your work with the public.

Reply: They look like nice specimens you collected.  I shared the images with paleobotanists at the Denver Museum of Nature & Science.  This is there reply, "From the pictures, it seems that the fossils contain a lot of organic debris, rather than wholly preserved leaf material.  The bug is nice.  This area was worked by DMNS volunteers in the late 90's, headed by Pat Ervin.  Geologically, Pulpit rock is coarse fan material that is in the basal portion of the Denver Basin's D1 sequence."

We already checked on your web site on Saturday [regarding Castle Rock dig - Sat 12/10/02], and it's really, REALLY good!   Even the pictures of us (especially because we know that the light was fading fast when you took them).  But seriously, your site is really well done, and really informative.

I am going to write a short description of our site visit for the Alberta Palaeontological Society newsletter when I get back to Alberta, and I'll let them all know about your web site.  Could I get copies of one or more of your images for inclusion in the article?  Perhaps a nice leaf or two, and that one of Regan and I in the quarry?

I am very familiar with your paleocurrents.com site--an excellent paleobotantical reference area, indeed.  Just yesterday, I posted to the newsgroup sci.bio.paleontology a link to your very nice Bonanza, Utah, Green River Formation page. I hope to visit that classic site someday... That perfect Macginitiea is simply extraordinary. I have seen excellently preserved Macginitiea from the early Middle Eocene Chalk Bluffs Flora (the extinct sycamore is of course named for Dr. MacGinitie, who first described the classic Chalk Bluffs Flora), western Sierra Nevada foothills, California, but few have compared to that Bonanza Green River specimen. Unbelievable preservation. Keep up the great work.

I just discovered the Denver Museum website and your site while on google.com looking up fossil plant information. This is really a great site!  The information and images are superb, and I appreciate being able to access your current research and see what is happening.

I am a natural science illustrator specializing in paleontology, and there will be a Guild of Natural Science Illustration conference in Denver next July. Maybe you already know about this, but they are looking for presenters from the Denver Museum of Natural History. I think it would be very interesting if you guys could give a talk on your Paleocene paleobotanical research, and perhaps how you use illustrators to make technical drawings as well as reconstructions such as these beautiful murals.

If you are interested, I could give your contact info to the organizers.

Thanks,

THANK YOU for this web site -- it is very nicely done! I just read about this Castle Rock project in an email publication CDOT puts out called "Road Quill", where it mentioned the Castle Rock excavation project this month (and a link to your site that doesn't work! - had an extra "." period at the end of the URL). But I looked it up and was very pleased to see what a well-designed site it is. I'm glad CDOT is involved with the Castle Rock rainforest project. I firmly believe that CDOT has an ongoing responsibility to contribute to the pool of knowledge when we come across natural sites that yield information about the earth's physical and/or social history. As a state governmental entity, we should not be just "about roads".

I may just check out the Museum's programs, too. I was fascinated by dinosaurs and the early evolution of the earth as a kid, and I'm due to retire in about 5-6 years. I should start checking into ways to keep the ol' brain in gear and do something useful. At the present time my supervisor and myself do computer support for the engineering branches of CDOT at the headquarters building. Some of that knowledge might come in handy too.  Do keep going!!!

What are you doing with the specimen which are not good enough or scientifically valuable enough to place in the museum's collections? Are the chunks of rock with fossils being left on the site so that there is some semblance of a fossil recod still there, or is it all being dismantled and destroyed?

Thanks, Charlene

Reply:  Though we are removing and studying thousands of fossils, the actual percentage of what we are removing is very small.  This was a large rainforest which covered a large area of land.  We are working on a single area that is exposed on a hillside below a railroad track.  The hillside is several hundred yards long and of that we've made about 11 quarries - each being about 6 feet wide.  So, yes, most of the fossil record still exists.  We have probably tapped a very small fraction of 1% of the total.  Please note that this area is Colorado Department of Transportation land and fossil collecting by the public is prohibited.  A permit is required from the State of Colorado to collect at the site.  Hope that answers your questions.  Thanks for writing.

Subject: Identifications?

Any chance that Dr. Johnson could be persuaded to identify the many fossil leaves in your image galleries? I mean, the fossils are nice to look at, but they'd be a whole lot more meaningful if we could learn just what kind of plant we're looking at. Just a thought, anyway.

Reply:  Great suggestion. I've been planning to get help on that for some of the morphotype images that I recently added.  One problem is that identification of most will take a very long time.  Some are known like the Platanus, Cycads, or Infructescence of Hamamelidacae (see the images at http://www.paleocurrents.com/castle_rock/gallery/2002_09_10/HTML/index.htm).  And, others we may casually call arctocarpus at the quarries, but they aren't true arctocarpus.

Castle Rock has been a treasure of new species - in fact, it is believed that most of the specimens are new to science.  The team is currently doing morphotype identification of the leaves using the Manual of Leaf Architecture, Smithsonian Institution, 1999, Published and distributed by the Leaf Architecture Working Group. If you're interested, it can be found at http://www.peabody.yale.edu/collections/pb/MLA/.

Unique specimens are identified using the techniques in this manual.  Then, they are assigned a morphotype number (e.g. CR097 - Castle Rock's 97th  morphotype).  With new species, that is probably all we can call them by without years of research and publications to formally name them.

I have been considering the Denver Basin for 20 years. I really like what you have offered here. There is a lot of information provided about what is a rather complicated and difficult geological structure, fossils and formations.

I do have one suggestion. You really don't have any kind of index.  It is a  typical web site constructed in a treelike manner connected by following (some say drilling into) link after link. You really do need an index or table of contents of some kind.  It could be constructed in the traditional book form (major parts [chapters or individual papers], the subdivisions of those into things that would be sections in a books chapter, and so fourth) or tree like, showing the actual links that are there. In any case this needs to be right at the top of the pile, or perhaps I should say, at the root of the tree.

Also, when you say "new" or "new addition", please add the date.

Anyway, please keep up keep up the good work. It clearly took a lot of effort to make this happen.

Reply:  Thank you for your feedback.  I will give the index some thought and make some changes.  I like the idea of putting the date next to "New" also.  Over the coming months, I should be adding more about the Denver Basin from other fossil quarries as well as geology.  It's a difficult balance between the work I'm doing for the website and the work in the field and museum.  It's a fascinating area though.  Thanks again for your feedback.
