Welcome to the Dallas Paleo Website

The Dallas Paleontological Society was founded in 1984 for the purpose of promoting interest in and knowledge of the science of paleontology.  It was intended by the founding members that the Society would be a network for the exchange of data between professionals and serious amateurs in this field.

Next Meeting: Just when you thought it was safe to go back in the water...

The next meeting of the Dallas Paleo Society will be on Wednesday, May 11th at 7:30 pm at Brookhaven College, Building H.  Our featured speaker will be Joseph Frederickson, a Ph.D. candidate in Ecology and Evolutionary Biology at the University of Oklahoma.  Joseph will be speaking on "The Lone Shark State: the story behind the discovery and description of a gigantic Cretaceous shark from Texas ".  DPS member Lance Hall helped excavate some of the specimens from the Duck Creek Formation in Fort Worth.  In honor of our speaker, bring your shark vertebrae and teeth specimens to show and tell, and let's see if we can document sharks from all the formations in north Texas.  Hope to see you and your sharkey finds at the meeting!

Over 100 attend Valley View/Spring Creek Field Trip

Over 100 enthusiastic fossil hunters showed up at our field trip to Valley View, TX this past Saturday.  Everyone went home with ammonites, and echinoids.  A full report will follow in a few days, but here are a few photos of some of the finds:

1)On the square at Valley View  2) Mortoniceras with rostrum, 

3) Eopachydiscus in situ  4)Macraster Mass Mortality Bedding Plane

5) Leptostyrax giant partial shark vert from Duck Creek FM

6) and 7) Treasured finds....Eopachydiscus

Thanks to Bob Williams for being our host and making arrangements with the land


Join us on our next trip this Saturday, April 23, in Brownwood, TX.

FOSSIL Project plans Webinars

Hello!  The FOSSIL Project, in partnership with the iDigBio Project and other organizations, is planning a series of free online webinars aimed at the amateur and professional paleontological communities.  This will be a monthly series, starting Summer 2016.  Webinars are online learning sessions led by a presenter with real-time input from participants.  Each webinar would be (no more than) an hour long, optimally with half of the time devoted to a lead presentation followed by questions and discussion.  We will likely use Adobe Connect™ to deliver the webinars; these will be recorded, archived, and freely available for non-commercial uses.  The webinars would be promoted broadly and open to anyone interested.  There would be no cost for attending, and participants could pick and choose which webinars they attend - or watch archived versions.  Participants would be expected to provide feedback about the webinars via an e-survey at the end of each session.

We need your help!  We want to make sure that the webinar series covers material that reflects the community’s desires.  To ensure this, we have created a survey.  Please complete the survey by May 10, 2016 (use link below for access).  The more responses we get, the better, so please forward this message to any interested folks you know.


Thank you for your help and suggestions as we prepare for this webinar series!  Please let me know if you have any questions or concerns.

Jacksboro Field Trip a Success

There were many on the Jacksboro trip that had never been to the area before.  The great thing about Jacksboro is the diversity of the specimens you can collect there.  Here are some items from Jacksboro.


1) Gonioloboceras 2) Mooreoceras 3) Strobeus sp. 4) Lyphophyllidum.spinosum 5) Domatoceras sp. or Titanoceras sp.  6) Otodus varibilis    

Arlington Archosaur Site raising funds

The Arlington Archosaur Site is running a small crowdfunding campaign to raise money to support scientific work at the site over the summer. DPS members have been instrumental to these discoveries since the AAS was found and we appreciate your help in continuing the excavation and study of this unique locality. The campaign will run until May 10 and we are part of a paleontology challenge group, with rewards going to projects with the most supporters, so donations of every amount help us reach this goal! We are already off to a strong start and I would like to keep this momentum going!

 Please follow this link to donate: https://experiment.com/projects/the-arlington-archosaur-site-a-unique-cretaceous-ecosystem-and-urban-fossil-dig

If you want to get more involved with the AAS we are looking for new dig volunteers. Please email arlingtonarchosaursite@gmail.com for more information if you are interested.

Were Dinosaurs Doomed Before the Asteroid?

Sauropod species, including large plant-eaters like Brontosaurus and Alamosaurus, shown here, may have started dying off more than 100 million years before the Chicxulub asteroid impact. Yet Alamosaurus fossils are found just below the worldwide layer of impact debris, indicating they were among the last surviving dinosaur species. (Credit: rDiBgd/Wikimedia Commons)

The age of the dinosaurs was growing stale long before that infamous impact.

A new study claims that dinosaurs were doomed to extinction before a city-sized space rock abruptly ended their reign some 66 million years ago. The analysis, published online Monday in Proceedings of the National Academy of Sciences, shows many species had already been dwindling for tens of millions of years.

First Fossilized Heart Of Prehistoric Animal Discovered

April 20, 2016  From www.sciencewr.com

In a breakthrough discovery, a perfectly preserved 3-D fossilized heart was found in an 113-119-million-year-old fish from Brazil called Rhacolepis, according to a report published in the journal eLife. The findings will help researchers observe the anatomy of an extinct group of fish and consequently understand the evolution of the first backboned animals as well as the development of the heart.

For the past decades, the fossil remains of vertebrates, or backboned animals, were studied mainly from their fossilized footprints or bones. It was believed that finding a well-preserved soft tissue in ancient fossils is impossible. Therefore, finding an absolutely intact fossilized heart in a 120-million-year-old prehistoric animal was a major discovery for researchers.

The new discovery was made by imaging a fossil concretized within limestone by applying synchrotron X-ray tomography down to 6µm sections.  The heart was then extracted part by part using software to digitally restore its features. The widely popular method is being used in paleontology for the past decade to understand the complex soft-tissue structures in fossils.

The discovery of the fossilized Rhacolepis heart is important as it shows the valve condition present in an ancient member of the ray-finned fish group. The heart pattern seen in the Rhacolepis represents a good intermediate condition between the most primitive and most advanced type, and simple patterns often have more complex and hidden meanings encapsulated in them.

"The discovery of complete soft tissues preserved as whole internal organs in a fossil was a bit of a Holy Grail for paleontologists, " said John Long, a paleontology professor at Flinders University, Australia in a recent article in The Conversation. "Such discoveries could contribute to understanding deeper evolutionary patterns as internal soft organs have their own set of specialized features." The find also indicates the immense possibilities of more discoveries of this kind in the future.

Annual Denton Creek Canoe Trip May 21st

Same song, 21st  verse is our usually annual row/paddle/float/drag down the lovely stream called Denton Creek between SH 407 (near Justin) and I-35W (just north of Texas Motor Speedway) all about 30 miles north of Fort Worth. Come join us for a bit of a different outing.  Click Here for details. EVERYONE planning to go MUST provide name and phone number whether you’re renting a boat or bringing your own – giving me your phone numbers. Reason is that the trip will be a last minute decision to go, cancel or revert to Plan B (a lake site for shoreline collecting, for example).

Tyrannosaur Tooth at Arlington Site

From the Arlington Archosaur Site Facebook page:

I've missed the last few due to a lot of work going on here. I've been waiting to post this for a while and I think today is a perfect opportunity to share with you a new theropod tooth that was discovered this past summer. The most exciting thing about this new tooth is we now know that it belonged to some type of tyrannosaur. Not T. rex, but a smaller, more primitive cousin. This is the earliest evidence of tyrannosaurs in this area! This tooth is very important for expanding our understanding of when tyrannosaurs first came to Texas, and from there perhaps, spread to other parts of eastern North America.

And keep your eyes on this page Monday when we'll make a big announcement!
