Who or what is "Dinny the Dino"?...

 

 

...a DGS mystery for over 60 years!

Preface    

     Welcome to a new format for fossils--the DMS "Fossil Forum"!  One of our newest student
members, Jennifer Anné has written on her experience of her study of a special dinosaur skeleton,
which has become a part of Delaware paleontological lore.

 

Introduction

     Welcome to our first Fossil Forum! 

     This month, we are investigating the mystery of an unidentified dinosaur specimen that has
rested in the Delaware Geological Survey basement for over half a century.  Enjoy!

Dinny, the Dinosaur of the University of Delaware

     After sitting in the basement of Penny Hall for over 60 years, the remains of Dinny the dinosaur
have finally begun to get the attention they deserve.  There are no records on who found them, when,
where, what formation, or what age, the hunt for the identity of the modge-podge of bones. Dinny is
an assemblage of haphazard bones that are being prepared by students at the University as part of
the Fossil Preparation course offered by undergraduate, Jennifer Anné.  This 1 credit course meets
once a week in the downstairs lab of the DGS for an hour and learns how to properly prepare fossils. 
Students learn about different glues and stabilizers, how to use tools such as an airscribe (something
like a mini jack hammer), and above all, the appreciation of getting the fossils from the ground to display.  Although Dinny is the main focus, students also prepare fossils from Sewell, NJ, fix specimens used
by the geology classes, and even offer to fix and stabilize people’s personal collections.  This gives the students a well-rounded experience in different forms of fossilization as well as dealing with different
types of matrix.

     Since there is no information on Dinny, the students must rely on every aspect of geology and
paleontology to do some hard core detective work.  Clay nodules in the hard sandstone matrix were
saved to be properly prepared to search for pollen.  The pollen will be identified by Dr. Pete McLaughlin
from the DGS, who apart from being a great palynologist, also is responsible for giving the students the
space in the DGS and helped in supplying them with many of the materials needed.  Pictures of the handwriting on some of the casts have been sent to someone at the Smithsonian for handwriting
analysis. An x-ray defraction sample will be taken to search for characteristic minerals that may identify
the formation.

     As of now, the consensus on Dinny is the he is a Titanosaur, a sauropod like Brachiosaurus. 
This is based on several characteristics including comparison of some of the bones with specimens
shown in The Thunderlizards, a book about sauropods that came out in 2005.  At least 2 of the bones
matched perfectly with those of Titanosaurus, part of a radius and ulna.  Other supporting facts for a
Titanosaur are that the bones are not hollow, show that the creature was a herbivore.  The bones show
a red mineralogy characteristic of the Morrison Formation, which is Late Jurassic in age and thus would
house Titanosaurus.   The final bit of evidence is the overall size of the bones, with one being over 3 feet
long and that is with a part missing from the end.

Invitation to Members

Members,

Want to see your name in print?  Want to co-author, contribute, or author a whole Fossil Forum article?  Well, this the forum for you!

And Members, if you have pictures, or a story you would like to share, please feel free to offer.  We'd like to post them for our mutual enjoyment.   Of course, you get full photo and author credit, and a chance to reach other collectors, hobbyists, and scientists.  We only ask that you check your facts, give credit where it is due, keep it wholesome for our Junior Members watching, and keep on topic regarding rockhounding.

You don't even have to be experienced in making a webpage.  We can work together to publish your story.  A handwritten short story with a Polaroid will do.  If you do fancier, a text document with a digital photo will suit, as well.   Sharing is the groundwork from which we can get your story out there.

Our club's webpages can reach any person surfing the net in the world, and even on the International Space Station, if they have a mind to view our website!

We are hoping for a possible tie-in to other informative programs upon which our fellow members might want to collaborate.  Contact any officer or board member with your suggestions.

Our next FF will be a surprise.  For 2006, we are waiting for your suggestions.  What fossil do you want to know more about?
