Ambulocetus is among the best-studied of Eocene cetaceans, and serves as an instrumental find in the study of cetacean evolution and their transition from land to sea, as it was the first cetacean discovered to preserve a suite of adaptations consistent with an amphibious lifestyle.
Guinness World Records claimed it was the largest known Triceratops skeleton, [62] with a skull reconstructed to be 2.62 metres (8.6 ft) long. Most expensive Triceratops sold, and most expensive fossil sold in Europe. [63] [61] Hector Deinonychus: Around 50% of a skeleton with 126 preserved bones, missing all or most of the skull
They greatly affected cetacean evolution , because they spread across Earth's oceans. [7] They had long snouts, large eyes, and a nasal opening located farther up the head than in earlier archaeocetes — suggesting they could breathe with the head held horizontally, similar to modern cetaceans — a first step towards a blowhole.
Spring in Duke Island Park showing invasive lesser celandine (Ranunculus ficaria). Numerous plants have been introduced to the US state of New Jersey in the last four hundred years, and many of them have become invasive species that compete with the native plants and suppress their growth.
The plant grows up to 0.4 m (1.3 ft). The flowers are white, pedicellate, with six obovate petals and bloom from May to July. [3] After it flowers, it bears dark blue/purple fruit with a white powdery coating from June to August. [4] Its stems are terete and grow 30–60 cm (12–24 in) long.
Zygorhiza, mounted skeleton. Basilosaurids ranged in size from 4 to 16 m (13 to 52 ft) and were fairly similar to modern cetaceans in overall body form and function. [ 7 ] Some genera tend to show signs of convergent evolution with mosasaurs by having long serpentine body shape, which suggests that this body plan seems to have been rather ...
Species of the infraorder Cetacea A phylogenetic tree showing the relationships among cetacean families. [1]The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years.

The Hadrosaurus foulkii Leidy Site is a historic paleontological site in Haddonfield, Camden County, New Jersey.Now set in state-owned parkland, it is where the first relatively complete set of dinosaur bones were discovered in 1838, and then fully excavated by William Parker Foulke in 1858.
