    The Rio Puerco Valley

    The Rio Puerco Valley was my introduction to fossils...it immediately caught my attention...lit a match...became a place I am always eager to revisit...search...learn about... ...and in roaming it, have learned about myself. Many of my adventures in the Puerco are posted here, here...here and here...and here. From here on out, my excursions will be shared here. May you find happiness in your hunting. -P.

    A plesiosaur tooth from Morocco ...

    ... But I don’t know the genus. It is from the upper Cretaceous, found in phosphate deposits from the Oulad Abdoun basin, Morocco. It is around 6cm in length.
  6. Could not resist collecting some more Trochactaeon snails at Breitenbach-11 in Kainach, Styria, Austria last Saturday (10/10/2020). Especially the upper T-bed contains rather well preserved (for the formation, of course ) snails. But always the right amount of weathering is needed (not too much, leads to disintegration of snails; not to less, they will adhere firmly to the rock). Still some potential there. Worked only with a screwdriver, needed only a few very gentle hammer taps. No prepping, just a short brush with a soft tooth brush. For more info about the area, have a look at my
  7. Just a few ammonites from my last hunt along with a cool rock .
  8. Hi all! The Aguja Formation matrix that I ordered from PaleoTex arrived on June 12th, but I decided to wait until school ended before I began the process of searching it. Well, school ended yesterday so I have begun the process today! My 5 pounds of matrix are currently soaking in a solution of baking soda and water (because the matrix arrived "unwashed"), but while stirring up the squishy contents with my hand, I found the following 3 items that I'd like your input on. Item #1: Could this be a ceratopsian spitter tooth??? @Troodon More to follow...
  9. Okay, this may be just wishful thinking, but a girl can hope, right? For your viewing pleasure is an Upper Cretaceous coprolite from the North Sulphur River in Texas, Ozan Formation, Talyor Shale. This little beauty has some unusual fish remains. Any chance this is a caudal fin from a coelacanth? The bones are pretty substantial compared to other fish bones I've seen in coprolites from the area. It does contain scales that are good sized and pretty transparent, with kind of a fingerprint pattern. Obviously, they may not be from the same prey item. Can anyone tell me if these are indeed coelaca

    Upper Cretaceous oddity

    While out in the Puerco, I smacked open a concretion to find an unfamiliar pattern. Any thoughts or ideas are greatly appreciated. The specimen is from the Upper Cretaceous (Turonian) Carlile Shale. It is layered and each layer has this pattern. I currently do not have a measurement but will do so. Thanks for taking a look.

    Triceratops Collar Piece?

    I have seen this item for sale and if genuine it would be a cool thing to add to the collection. But can it be identified as a triceratops collar piece with any certainty? The description says [it is a Triceratops collar fragment from the Hell Creek Formation in Montana, USA].

    Atco Peculiarity

    In June of 2018, Kieth Minor alerted me to a new apartment complex that was being developed in the middle Atco Formation of North Texas. They were cutting a huge cubic area of rock out of a hillside, piling up multiple large mounds of Atco which seemed to be begging for someone to carefully search out their freshly exposed contents. On the 15th of that month we got to the site, Kieth asked permission of the site foreman for us to carefully take a look around during the crew's work hours, and we made our way into the pit. We were on a mission to save as many ammonites as we could.

    From the album: Mancos Shale - Grand Junction, CO

    Marine burrow. Found this down in the Mancos shale, loose. Possibly from the overlying Mesaverde formation. I have seen many burrows in the Mesaverde sandstone.

    Mosasaur or Plesiosaur?

    I found a tooth in Bladen County, NC at a site on the Cape Fear River near Elizabethtown. The site is Upper Cretaceous, and is Upper Campanian in age. It's in the Black Creek Group. I know that the tooth isn't in the best of shape, but hopefully is identifiable. All the Mosasaur teeth I had collected there before are a black color. I noticed this tooth is also curved from side to side. I don't know if it's a Plesiosaur or Mosasaur tooth. Both have been found at this site, but the Plesiosaur is far less common.

    Found Some Bone Today

    Hey folks, Here is a bone I found today. The photo shows it in situ as it was slowly sliding down a slight grade. The area where it was found does not permit collection by citizens so it remains where it was found. The area where it was found is along the ancient shoreline of the Western Interior Seaway on the west bank where the shoreline ebbed and flowed to engulf the immediate area, only to later be dry land at essentially the same level of strata. In the same immediate area where this was found, also today, I located fossilized stromatalite (a water bacteria), and foss
  16. Friends, I seem to collect lots of petrified wood in my nearly-every-weekend outings into the oil patch in the county where I live. Much of what is found are small little bits and pieces and a whole lot of it is really pretty. Some I will try to identify and those may earn their own topic entry, however, others are just nice little pieces that I cut up on my saw and will post the photographs here for y'all to look at. They are just too pretty to not share, you know? All those entered under this topic will be found near my home unless otherwise notated. Some of the petrified wo

    Fossilized Conifer, anyone?

    Some petrified wood found in northwestern New Mexico, San Juan Basin, Upper Cretaceous, Kirtland Formation a couple of weeks ago. The cut slabs are from a log about 6-inches in diameter and my best guess is conifer only because most everything else in that area turns out to be conifer, specifically, Cupressinoxylon sp. Any other opinion about species would be welcome. There are several nice agate bands running through the length of the log and are clearly visible here. The first slab is dry and the second is wet.

    Gotta start somewhere

    Hi. Total newbie here. But interested in what I see as I have been lurking this site for 5 years or so. I have acquired some basic prep tools and want to practice a bit of matrix removal to develop a feel for the rock and tools before I start anything important (to me at least). I picked up a few rocks yesterday from the Nanaimo Formations, upper Cretaceous, Campanian the map says. It would be handy to know what I am looking at so I could Google some images and know what to look for as I uncover things. If anyone would care to identify a few things, I would be grateful.
  19. I posted this image in the prep thread and I was widely stated to be an Ichnofossil of infilled burrows. I really don't want to be "that guy" that questions expert opinions, but I'm curious; the burrow seems to have attached branches and areas of tiny "grassy" masses adjacent to it. Could they be crinoid segments/branches and pinnules? I have seen photos of chondrites that have the same kind of appearance. I include 3 of my photos, including one through the eyepiece of my scope, and one internet photo of crinoid pinnules. Thanks. I'll happily accept your opinions, go away now, and not be

    NM Conifer from Upper Cretaceous

    A couple of photos showing an unknown fossilized conifer tree located this past November (2019) in northwestern New Mexico, Kirtland Formation, Upper Cretaceous. Sorry for no scale but the specimen is about 13 inches (33 centimeters) long. Also included is a photo of my dig where I removed this specimen as a piece of something larger. You will see this specimen limb is quite compressed, something common for petrified wood found in that area of New Mexico. I have tentatively identified the specimen as a conifer using a DinoLite (see photo). I am seeking help with addi

    Sponge? Coral? None of the above?

    Found in northwestern New Mexico in an Upper Cretaceous area. Specimen was wetted with water to bring out detail.

  23. I have been doing more research on my unidentified Middle/Upper Coniacian heteromorph ammonite that I posted pictures and information on here, and with lots of papers and information from Keith Minor I think that I have narrowed it down to two ammonite genera, Neocrioceras and Pseudoxybeloceras. He sent lots of very helpful papers including Kennedy and Cobban's 1991 paper Coniacian ammonite faunas from the United States Western Interior. It includes pictures and information on 3 species of Neocrioceras and one species of Pseudoxybeloceras from the Coniacian Western Interior. Keith also emailed

    New Tyrannosauroid from China

    A new Tyrannosauroid is described in this paper, unfortunately its paywalled. I show it not just because its new but once thought to be aTarbosaurus sp, see photos below. So until its studied, reviewed and published identifications are just preliminary. So let me welcome Jinbeisaurus wangi the first theropod dinosaur so far found in Shanxi Province, Huiquanpu Formation Scale: 1 meter https://www.sciencedirect.com/science/article/pii/S0195667119301909 Some poor screenshots of images Much better Q photos thanks to Jim Kirklan
