Modern tropical forests harbor an enormous diversity of squamates, but fossilization in such environments is uncommon and little is known about tropical lizard assemblages of the Mesozoic. We report the oldest lizard assemblage preserved in amber, providing insight into the poorly preserved but potentially diverse mid-Cretaceous paleotropics. Twelve specimens from the Albian-Cenomanian boundary...

Levnesovia transoxiana gen. et sp. nov., from the Late Cretaceous (Middle-Late Turonian) of Uzbekistan, is the oldest well-documented taxon referable to Hadrosauroidea sensu Godefroit et al. It differs from a somewhat younger and closely related Bactrosaurus from Inner Mongolia (China) by a tall sagittal crest on the parietals and the absence of club-shaped dorsal neural spines in adult specime...

The Cenomanian-Turonian period recorded one of the largest disruptions to oxygen and carbon cycles, Oceanic Anoxic Event 2 (OAE2, 94 Ma). This event is global, yet paleo-reconstructions document heterogeneous ocean oxygenation states sedimentary contents, temporally spatially, suggesting that several mechanisms are at play. To better understand long-term controls on oceanic initial conditions p...

We report the Narmada Seaway began in India during largest global sea-level transgression and Oceanic Anoxic Event 2 (OAE2) δ13C excursion late Cenomanian to early Turonian. The progressed eastward Turonian-Coniacian reached Jhilmili by end of Maastrichtian. During this time Godavari Seaways may have joined via Narmada-Tapti rift formed a Trans-India Seaway. history major seaway is entombed fos...

The nature of the Cenomanian–Turonian Oceanic Anoxic Event (CTOAE) and its δ13 C Excursion is considered in light (1) stratigraphical framework which CTOAE developed European shelf seas, (2) conclusions that can be drawn from new detailed investigations Chalk succession at three locations England, Melton Ross Flixton Northern Province where organic-rich ‘black bands’ are present, Dover Southern...
