Two Sections Of The Upton Ancient Trackway, Found Near Magor Pill, 2400 Years Old, Newport Museum and Galleries, Wales

This is a centipede track. Middle or Late Triassic. 240-220 mya. I spotted this at my neighbor’s property about half mile away and he let me drag it home.

Prorotodactylus

Prorotodactylus is an ichnofossil from a Dinosauromorph, and so we’re doing it here during our coverage of Dinosauromorphs! It is a footprint known from the Holy Cross Mountains of Poland. It is known from the Early and Middle Triassic, so sometime between 251 and 247 million years ago. As such it helps to provide more evidence to the idea that Dinosaurmorphs evolved much earlier than previously supposed - instead of evolving midway through the Triassic, the general group must have evolved close to the start of the Early Triassic, or potentially even earlier, right in the crux of the Permian-Triassic mass extinction event. 

Protodactylus are tracks made by a small quadrupedal animal with a long stride, with the hind feet placed on the same line as the fore feet. it had claws on its feet and it shows distinctly Archosaurian features, with a narrow trackway and a particular pace angle that showed that Protodactylus had an erect gait like later Dinosaurs rather than a sprawling one, and also a digitigrade posture like Dinosaurs did. In fact, its tracks line up fairly neatly with Lagerpeton, and could have been made by an animal similar to Lagerpeton. It was probably transitioning to a bipedal form of locomotion.

The Goldcliff Bronze Age Boat Plank, Newport Museum and Galleries, Wales

One of two Bronze Age sewn boat planks reused as an ancient trackway

The plank is part of a sewn boat which would have been held together by willow ropes threaded diagonally through holes. The central section was removed (and replaced) for tree-ring dating, which places the construction of the boat at around 3,100 years ago.

A picture of my chirotherium trackway site. Everything in front of the truck has been excavated. The truck is on the rocks of the lowest track layer. Behind the truck some of the second upper track layer is uncovered but not excavated. The leading edge of each layer goes from solid rock to a section of these loose individual tracks which I call Rex chunks - separate tracks from Chirotherium rex. The time period between the two layers could range from a couple hundred to maybe a thousand years, so very close in time.

Route between Gaping Gill and Ingleborough Trail, Yorkshire Dales.

I visited here in Spring in full sun. Today, after a sequence of heavy storms, the contrast of many fallen trees and heavy fog was stark.
