  1. Petrified Wood from Triassic in Pennsylvania

    Here are 3 medium size specimens of petrified wood that I found in the Newark Basin Triassic sedimentary deposits in southeastern Pennsylvania. They show a variety of color. Quarter coin is for scale. This material is rather scarce.
  2. I found 4 nice good-size specimens of petrified wood, from the Newark Basin Triassic sedimentary deposits, in southeastern Pennsylvania. Photo shows that all pieces are a light chocolate brown color. There is a quarter coin for scale. These are from the same location where I previously found two large specimens, which I posted a few years ago. This material seems to be rather scarce.

  5. Quick question for the experts: I've found a number of marine fossils in Newark Supergroup locations- corals, crinoids, brachiopods, yet I've read that the formation is non-marine. I'm told they could be glacial deposits. I also recall that Coelacanths have been found which I assume were marine. Was the formation marine or not? Or both? Thanks in advance!

  10. Unidentified fish Skull

    From the album Fossildude's Late Triassic Lockatong Formation Fossils

    This skull will need to be prepared to find out what it is. It looks a bit too narrow to be from Diplurus newarki, (although, it could be) . It could also possibly be from the early ray finned fish, Turseodus sp. or Synorichthys sp., which are known from the same strata. Newark Supergroup, Newark Basin, Late Triassic, Lockatong Formation. North Bergen New Jersey. Granton Quarry.

  11. Double skulls

    From the album Fossildude's Late Triassic Lockatong Formation Fossils

    A small plate with two skulls of the coelacanth, Diplurus newarki. The one on the bottom shows oblique dorso-ventral crushing. Late Triassic, Lockatong Formation, North Bergen, NJ,

  12. Hello all! Recently, I had the chance to meet up with a few forum members, and hunt the historic Granton Quarry, in North Bergen NJ. Last Monday, March 31st, I was up at the crack of dawn, 4:00 am, to hit the road and meet my partner for today, forum member Jeffrey P, in Newburgh, NY. I left my house in central Connecticut at 4:15 am, eager to be on the road, and heading towards the Triassic exposures of the Lockatong formation. An hour and a half later, after encountering heavy downpours and sporadic showers, I arrived at the appointed meeting place, a McDonalds parking lot, just off of Interstate 84. Meeting time was 6:00 am, and I arrived around 5:45am. Overly anxious? Not me. I was a little concerned about the weather, as ice pellets were beginning to hit my windshield as I waited for Jeff to arrive. Oh boy. Jeff showed up just after 6:00am, and after our initial greetings, and moving his gear to my truck, we got on our way. Jeffrey and I had collected together before, at my fossil fish site in Connecticut, so the trip down to North Bergen was a fun time talking over our expected strategies for this site, and how different this site was from my usual stomping grounds. We hit a bit of traffic heading into North Bergen, and arrived at our destination, around 7:20 am. Now, … Jeffrey had made two previous scouting expeditions to the site, and had a hunch on where we might find some productive layers of fossils. He had scored some clam shrimp and even had a very nice and possibly complete Diplurus newarki, a Triassic coelacanth! We were both hopeful, but realistic as the Newark Supergroup is notoriously hit or miss. For those unfamiliar with the area, the old Granton Quarry is gone, and on top of what was the main quarry floor, a Lowes Home Improvement Center now resides. There are still exposures of the Lockatong accessible to the north of the actual building., however. This exposure was our target. We stopped in to the Lowes, and met with the manager, Ray, who was perfectly willing to allow us to collect from the exposures on their property, so long as we stayed out of the way of any pending deliveries. We assured him we would be as unobtrusive as possible, and having received permission to hunt the exposure,, headed back to the car to get our gear. At this point, the other half of our collecting team arrived. John (Flyguy784) and his buddy Ken. I have been friendly with John since I joined the Forum back in 2010, and we have conversed fairly regularly, having bonded over our mutual frustration over hunting the Newark Supergroup. John is more of a plant guy, but we had talked in the past of a Granton trip, and when I mentioned to him that I was planning on going, he wanted to come up, if only just to get a chance to collect together. Meeting him, and putting a face to the name was a most welcome part of this trip, and we happily exchanged some fossils between us. It was now around 7:55, and we decided to gear up, and check some of the lower exposures, to see what could be found. The sky was gloomy looking, a light drizzle was falling, and the wind was blowing cold – a gray and fairly miserable start. Water was streaming off of the rocks above, in little runnels which felt great, sliding down your back. In the past, the Granton Quarry has yielded assorted fish, reptile/dino footprints, a little plant material, and some reptile material, including phytosaur teeth and coprolites, a gliding lizard (Icarosaurus) aquatic lizards, (Tanytrachelos) . We all had high hopes, but they were realistically tempered by our various experiences with hunting similar Newark Supergroup sites in the past. We collected the in the black and gray shales infrequently finding bits and pieces of both clam shrimp, and coprolites. Things continued in this vein for a few hours. We finally started to find assorted disarticulated bones of the coelacanth Diplurus newarki! Eureka! By this time, the rain had stopped, the sun came out, and the temperature was rising, steadily. At this point, we narrowed down the hunting to the lower few inches of a seam of black shale, the lower 2 inches of which were extremely friable, and nearly impossible to get out of the wall in any decently sized slabs. After finding a number of cool coelacanth bits, coprolites, and Estheria ovata clam shrimp slabs, between us, we decided around noon-thirty-ish to take a break for lunch, and retired to our cars in the Lowes lot. We snacked, talked fossils, and other various sundry things. An enjoyable time to be sure. We soaked up the sun, and enjoyed it’s warmth on our faces. At least my feet were no longer numb from the earlier cold! My companions were all amiable, and we enjoyed the time together. This is the type of outing that can be enjoyed, whether finding anything, or not. But, we were finding things, so we got back too it. We then decided to take the folding ladder I had brought, and try to access the higher layers of black shale which Jeffrey had managed to climb up to on a previous excursion, and remove a bit of shale that had yielded his Diplurus coelacanth. We set the ladder up, and took turns removing shale, and bracing the ladder for each other. When we got tired of removing rock, we stopped, took a break to split what we had removed, and then switched places. This garnered us some larger slabs, that, while they didn’t provide us with any complete fish, did reward us with some mortality plates of the Estheria ovata, and some more bits and pieces of Diplurus newarki. We continued in this way, while John and Ken scouted some of the lower seams of black shale. Time, as is always the case, flew away from us, and before we knew it, 4:00PM was approaching, and we needed to leave by then to make it home at a reasonable time. We packed up our things, said our goodbyes, and got on our way. Traffic leaving Jersey was smoother than coming in, so we were back to the McDonalds in Newburgh just around 5:00 PM. Jeff and I said goodbye, and went our separate ways. I headed home, to be stymied getting to the Beacon Bridge, for about a half an hour …just to get 3.5 miles or so. I finally arrived home to Connecticut at around 7:30 pm, excited by my finds and a successful hunt in the Lockatong Formation – The Newark Supergroup had blessed me with a few Upper Triassic finds for my collection. Thanks for looking – enjoy the pics. Regards, John (Flyguy 784- background) and JeffreyP (foreground) One area we tried to attack Continued...
