  1. Finally getting round to identifying some finds from over the years at different sections of Big Brook, NJ. I'm going to try and post them in separate topics. The white sea urchin spine is distinctive, but what are these other things? They have similar dots in lines, but the lines are much more spread apart. See that they have pointed ends and one has a wider end. They are about 2-4mm in diameter. Also, any idea or pointers as to what species the Sea Urchin spine could be? I haven't found an easy identification guide on the web yet.

  3. I finished my book and placed a order with my printer. I will have copies in my hand Nov 8th, 2016. Fossil Echinoids of Texas A Monograph of Fossil Sea Urchins William R. Thompson, Jr. www.echinoids.com bill@echinoids.com 432 pages over 99,000 words 237 species of Texas echinoids 1294 Color Photos 100 Existing Type specimens 46 New species and 1 new genus. This work aspires to be as thorough and detailed as possible with photos included for all species. All were photographed in high resolution color, with regular echinoids from the adoral, aboral, lateral ambulacral, and lateral interambulacral views. Irregular echinoids were photographed in adoral, aboral, lateral, anterior, and posterior views. In most cases, a single specimen is used to illustrate each species. One hundred of the specimens photographed were type specimens from the University of Texas Non-vertebrate Paleontology Lab, Louisiana State University Museum of Natural Science and the National Museum of Natural History (Smithsonian). Where types were unavailable, representative specimens were used from both institutions and private collections. Two specimens were contributed by the Mississippi Museum of Natural Science. Four of the representative specimens are from the Akers Collection which is currently owned by Chris Garvie. Many specimens are from the Frank Crane Collection which is currently owned by his son Dr. Stephen Crane. The remaining species are from private collections of William R. Thompson, Jr., Ed Elliott, Chris Garvie, Ron Root, Terry Stephenson, John Hinte, Mike K. Smith, Danny Harlow, James Costabile, Dave Hayward, Paul Hammerschmidt, Linda Farish, Dr. Stephen Crane, Frank Holterhoff, and Raul & Carlos González of the website erizosfosiles.jimdo.com. Each species is described in detail. If the original description was available, that text was included and credited. Descriptions which are protected by copyright laws or not available were not included in this publication. Instead, those species' descriptions and the new species' descriptions are the author's.

  4. A new, photo heavy tome covering Cretaceous echinoids of Texas is now available for preorder, and I'm announcing this on behalf of my good friend, author Bill Morgan. In his own words: Coming June 2016 Collector’s Guide to Texas Cretaceous Echinoids provides Texas Cretaceous Echinoid enthusiasts the tools to identify and understand these abundant rich fossils. With much of the scientific literature decades old, Collector's Guide to Texas Cretaceous Echinoids will be of interest to the beginner or advanced collector as well as the new student of invertebrate paleontology who seeks detailed and up-to-date insight into the morphology, classification, and identification of Cretaceous age echinoids. The abundance, quality of preservation, and aesthetic ornamentation of these fossils make them widely sought after by collectors and paleontologists alike. Readers are given a brief description of the climatic events believed responsible for the formation of these marine deposits followed by an introduction to the morphology and biology of echinoids including the unique features which separate regular from irregular forms. Key features: · More than 350 high-quality color photographs, many featuring major profiles of each species · Glossary of key terms; new terms are bolded in text and brief definitions provided in first appearance · Extensive bibliography provided for those seeking deeper research About the Author: William W. Morgan holds a PhD in anatomy and physiology from Indiana University in Bloomington. For forty years he was a neuroscientist and a teacher in the Department of Cellular and Structural Biology at the University of Texas Health Science Center in San Antonio, where he was a professor from 1981 until his retirement in 2011. Morgan is the author of Collector's Guide to Crawfordsville Crinoids.
  5. Echinoids and Bivalves, Malta

    Hi, I would really appreciate some help with these fossils. They were found in the Lower Coralline Limestone stratum (Miocene) in what is called the Scutella bed (due to the abundance of Scutella subrotunda). I apologize for not including some sort of scale. Thanks
  6. Texas Hill Country Hunting

    A friend found out about my hobby of fossiking (particularly urchins) and says "oh, there are hundreds of the round urchins on my property, come on out!" So, I did and was initially disappointed to find out that what he thought were round urchins, were in fact algal fruiting bodies or porocystis globularis (as I discovered a while back when I first found the fossil forum, thinking I had some cool eggs....) So finding literally hundreds of these globularis was quite cool, but I wanted urchins! Now, also, there were urchins. Lots and lots and lots...of heart urchins. Which I like. A lot. But I also find them quite frequently where I am. I was wanting ROUND urchins! I havn't found but a few of those in my huntings. So I kept hunting. And was rewarded with a few small but nice phymosoma texanum round urchins. Yay!! And a mess of nice gastopods and bivlaves (some really adorable, yes, adorable, small deer heart clams) .All in all, a good days hunt!
