which plants were found on the second ancient continent?
Pine trees, flowering plants.
Laurasia
Pine trees evolved in the early Mesozoic c. 250 Mya and the pine genus originated in Laurasia in the Early Cretaceous c. 130 Mya in competition with faster growing flowering plants.

From geologist Alexander Philipov Postels and artist who worked with Ruprecht, while the specific name, "palmaeformis", describes the alga's superficial similarity in appearance to true palms. where is it found?

Yes, the blades are sometimes used in certain dishes are any animal fossils also found in the first place where these fossils are sound? Yes, Monte Bolca has crustaceans, jellyfish and polychaete worms what are its geological features? It was uplifted from the Tethys Ocean floor during the formation of the Alps, in two stages: one 24 million years ago, and one between 30 and 50 million years ago. where is this ocean? Between the ancient continents of Gondwana and Laurasia what are the subdivisions of the ocean? he eastern part of the Tethys Ocean is sometimes referred to as Eastern Tethys. The western part of the Tethys Ocean is called Tethys Sea, Western Tethys Ocean, or Paratethys or Alpine Tethys Ocean. when was the first ancient continent mentioned above formed?

Laurasia [SEP] Flora and fauna
Crocodiles also diversified during the Early Cretaceous but were divided into Laurasian and Gondwanan populations; modern crocodiles evolved from the former. The distribution of the three major groups of dinosaurs – the theropods, sauropods, and ornithischians – was similar that of the crocodiles. East Asia remained isolated with endemic species including psittacosaurs (horned dinosaurs) and Ankylosauridae (club-tailed, armoured dinosaurs).
