SummaryNumerous gutter-like furrows, up to 60 cm wide and up to 9 m long are preserved at the interface “Macrocephalus Beds”/“Callovian Marl” over a surface of 20 by 200 m. They are interpreted as feeding traces made by large marine vertebrates, most likely plesiosaurs and ichthyosaurs searching for food in the lime mud of the shallow Middle Jurassic sea floor. Possible prey animals were infaunal invertebrates (crustaceans) which produced an intricate meshwork of burrows (mainlyRhizocorallium… 
The ichnogenus Rhizocorallium: Classification, trace makers, palaeoenvironments and evolution
Rhizocorallium is one of the oldest known trace fossils, with wide distribution through the Phanerozoic and all over the world. Originally introduced from the epicontinental Triassic of central
New insights on the systematics, palaeoecology and palaeobiology of a plesiosaurian with soft tissue preservation from the Toarcian of Holzmaden, Germany
TLDR
The plesiosaurian specimen SMNS 51945 found in this area is a juvenile individual consisting of a partial, crushed skull and an exquisitely preserved post-cranial skeleton, confirming that wing area in plesioaurians was much larger than that suggested by skeletal remains alone.
Osteology of Rhomaleosaurus Thorntoni (Sauropterygia: Rhomaleosauridae) from the Lower Jurassic (Toarcian) of Northamptonshire, England
ABSTRACT This paper describes the holotype of Rhomaleosaurus thorntoni (NHMUK PV R4853) from the upper part of the Whitby Mudstone Formation (Toarcian) of Kingsthorpe Hollow, Northamptonshire,

Sulcolithos variabilis igen. et isp. nov.: grooves on firm and hard bedding surfaces
The trace fossil Sulcolithos variabilis igen. et isp. nov. is described from the Middle Triassic (Ladinian) Muschelkalk Group of Germany. The groove-like structures occur on the surface of limestone
Rare evidence of a giant pliosaurid-like plesiosaur from the Middle Jurassic (lower Bajocian) of Switzerland
Here, we describe part of a large-bodied macrophagous plesiosaur jaw from the lower Bajocian (Middle Jurassic) Passwang Formation near Arisdorf in the Basel-Land canton of Switzerland. The specimen
PLEISTOCENE WALRUS HERDS IN THE OLYMPIC PENINSULA AREA: TRACE-FOSSIL EVIDENCE OF PREDATION BY HYDRAULIC JETTING
Abstract Quarry walls in Pleistocene marginal-marine coarse-grained deposits adjacent to Willapa Bay, Washington, expose a contact from which unusual sedimentary structures originate. These
Nothosaur foraging tracks from the Middle Triassic of southwestern China.
The seas of the Mesozoic (266-66 Myr ago) were remarkable for predatory marine reptiles, but their modes of locomotion have been debated. One problem has been the absence of tracks, although there is

Swimming capabilities of Mesozoic marine reptiles: implications for method of predation
TLDR
Estimating the total drag and the amount of energy available through metabolism, the maximum sustained swimming speed was calculated for 115 marine reptile specimens and suggests that the long-bodied forms probably used an ambush technique to capture prey, to maximize the range of possible prey and to minimize competition with the faster pursuit predators.
