Eucommia ulmoides is a species of small tree native to China. It belongs to the monotypic family Eucommiaceae. It is considered vulnerable in the wild, but is widely cultivated in China for its bark and is highly valued in herbology such as traditional Chinese medicine.
Maclura tricuspidata is a tree native to East Asia, occasionally grown for its fruit, somewhat similar to that of the related mulberry. It is also known by common names including cudrang, kujibbong, storehousebush, mandarin melon berry, silkworm thorn, zhe or che, and Chinese mulberry. It grows up to 6 m high.
Altingiaceae is a small family of flowering plants in the order Saxifragales, consisting of wind-pollinated trees that produce hard, woody fruits containing numerous seeds. The fruits have been studied in considerable detail. They naturally occur in Central America, Mexico, eastern North America, the eastern Mediterranean, China, and tropical Asia. They are often cultivated as ornamentals and many produce valuable wood.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1997.

The Tlayúa Formation is an Early Cretaceous geological formation near Tepexi de Rodríguez, Puebla.
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation, named for the type location designated in 1962, Klondike Mountain north of Republic, Washington, is composed of volcanic rocks in the upper unit and volcanics plus lacustrine (lakebed) sedimentation in which a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs.
Eucommia is a genus of small trees now native to China, with a fossil record that shows a much wider distribution. The single living species, Eucommia ulmoides, is near threatened in the wild, but is widely cultivated in China for its bark, and is highly valued in herbology such as traditional Chinese medicine.
Eucommia eocenica is an extinct species of flowering plant in the family Eucommiaceae. E. eocenica is known from fossil fruits found in the middle Eocene Claiborne Formation deposits of the southeastern United States. E. eocenica is one of five described fossil species from North America assigned to the modern genus Eucommia. The other species are E. constans, E. jeffersonensis, E. montana, and E. rowlandii.
Eucommia montana is an extinct species of flowering plant in the family Eucommiaceae. E. montana is known from fossil fruits found in Eocene deposits of the northwestern United States southeastern British Columbia south to Oregon and east to Montana and Colorado. E. montana is one of five described fossil species from North America assigned to the modern genus Eucommia. The other species are E. constans, E. eocenica, E. jeffersonensis, and E. rowlandii.
Eucommia jeffersonensis is an extinct species of flowering plant in the family Eucommiaceae. It is known from a fossil fruit found in latest Eocene deposits of Oregon, United States. E. jeffersonensis is one of five described fossil species from North America assigned to the modern genus Eucommia. The other species are E. constans, E. eocenica, E. montana, and E. rolandii.
Eucommia rolandii is an extinct species of flowering plant in the family Eucommiaceae. E. rolandii is known from four fossil leaves found in Middle Eocene deposits of British Columbia, Canada and Mississippi, United States. E. rolandii is one of five described fossil species from North America assigned to the modern genus Eucommia. The other species are E. constans, E. eocenica, E. jeffersonensis, and E. montana.
Acer traini is an extinct maple species in the family Sapindaceae described from isolated fossil samaras. The species was described from Miocene-aged fossils found in Canada and the United States of America. It is one of several extinct species placed in the living section Glabra.
Hymenaea mexicana is an extinct legume species in the family Fabaceae described from a series of isolated fossil petals, leaflets, and amber. The species is known from a group of Late Oligocene to Early Miocene locations in southern Mexico. It is one of two extinct Hymenaea species placed close to the living species Hymenaea verrucosa and along with Hymenaea allendis, is one of the two extinct species which have been found in Mexican amber.
Hymenaea allendis is an extinct legume species in the family Fabaceae described from a single isolated fossil flower in amber. The species is known from a Late Oligocene to Early Miocene location in southern Mexico. Unlike the coeval extinct species Hymenaea mexicana and Hymenaea protera which are placed closer to the living species Hymenaea verrucosa of Africa, H. allendis is closer in relation to the neotropical species of Hymenaea.
The Allenby formation is a sedimentary rock formation in British Columbia which was deposited during the Ypresian stage of the Early Eocene. It consists of conglomerates, sandstones with interbedded shales and coal. The shales contain an abundance of insect, fish and plant fossils known from 1877 and onward, while the Princeton Chert was first indented in the 1950's and is known from anatomically preserved plants.
Cipactlichthys is a genus of extinct holostean fish from the Lower Cretaceous of Mexico. The only known species is Cipactlichthys scutatus.
Aphaenogaster praerelicta is an extinct species of ant in the subfamily Myrmicinae known from a solitary Late Oligocene to Early Miocene fossil found in Mexico. At the time of description A. praerelicta was one of three Aphaenogaster species known from Mexico.
Casaleia is an extinct genus of ants in the formicid subfamily Amblyoponinae described by Pagliano & Scaramozzino in 1990 from fossils found in Europe. The genus contains four species dating from the Eocene to Miocene, Casaleia eocenica, Casaleia inversa, Casaleia longiventris, Casaleia orientalis.
