The year 1915 involved numerous significant events in science and technology, some of which are listed below.
Bahariya Oasis is a depression and a naturally rich oasis in the Western Desert of Egypt. It is approximately 370 km away from Cairo. The roughly oval valley extends from northeast to southwest, has a length of 94 km, a maximum width of 42 km and covers an area of about 2000 km2.
Aegyptosaurus is a genus of sauropod dinosaur that lived in what is now Africa, around 95 million years ago, during the Late Cretaceous Period.
Bahariasaurus is an enigmatic genus of large theropod dinosaur. The genus is known to have included at least 1 species, Bahariasaurus ingens, which was found in North African rock layers dating to the Cenomanian and Turonian ages of the Late Cretaceous. The only fossils confidently assigned to Bahariasaurus were found in the Bahariya Formation of the Bahariya oasis in Egypt by Ernst Stromer but were destroyed during a World War II bombing raid with the same raid taking out the holotype of Spinosaurus and Aegyptosaurus among other animals found in the Bahariya Formation. While there have been more fossils assigned to the genus such as some from the Farak Formation of Niger, these remains are referred to with much less certainty. Bahariasaurus is, by most estimations, one of the largest theropods, approaching the height and length of other large bodied theropods such as Tyrannosaurus rex and the contemporaneous Carcharodontosaurus. The aforementioned estimations tend to put it at around 11–12.2 metres in length and 4-4.8 tonnes in overall weight.
Deltadromeus is a genus of theropod dinosaur from the Aoufous Formation of Morocco.
Janenschia is a large herbivorous sauropod dinosaur from the Late Jurassic Tendaguru Formation of Lindi Region, Tanzania around 155 million years ago.
Anoplosaurus is an extinct genus of herbivorous nodosaurid dinosaur, from the late Albian-age Lower Cretaceous Cambridge Greensand of Cambridgeshire, England. It has in the past been classified with either the armored dinosaurs or the ornithopods, but current thought has been in agreement with the "armored dinosaur" interpretation, placing it in the Ankylosauria.
Sigilmassasaurus is a controversial genus of spinosaurid dinosaur that lived approximately 100 to 94 million years ago during the Late Cretaceous Period in what is now northern Africa. Named in 1996 by Canadian paleontologist Dale Russell, it contains a single species, Sigilmassasaurus brevicollis. The identity of the genus has been debated by scientists, with some considering its fossils to represent material from the closely related species Spinosaurus aegyptiacus, while others have classified it as a separate taxon, forming the clade Spinosaurini with Spinosaurus as its sister taxon.
Stomatosuchus is an extinct stomatosuchid neosuchian from the Late Cretaceous (Cenomanian) of Egypt. Much of what is known about Stomatosuchus has been inferred from the related genus Laganosuchus.
Schizorhiza is an extinct genus of schizorhizid sclerorhynchoid that lived during the Late Cretaceous. It contains one valid species, Schizorhiza stromeri. It lived from the Campanian to Maastrichtian, and its fossils have been found in Africa, the Middle East, North America, and South America.
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 1932.

Libycosuchus is an extinct genus of North African crocodyliform possibly related to Notosuchus; it is part of the monotypic Libycosuchidae and Libycosuchinae. It was terrestrial, living approximately 95 million years ago in the Cenomanian stage of the Late Cretaceous. Fossil remains have been found in the Bahariya Formation in Egypt, making it contemporaneous with the crocodilian Stomatosuchus, and dinosaurs, including Spinosaurus. It was one of the few fossils discovered by Ernst Stromer that wasn't destroyed by the Royal Air Force during the bombing of Munich in 1944. The type species, L. brevirostis, was named in 1914 and described in 1915.
Paranogmius is an extinct genus of prehistoric bony fish that lived during the Cenomanian. It is known from only 2 partial skulls and several dorsal vertebrae discovered in the Bahariya Formation that was destroyed during World War II. Since then, no more fossils have been discovered. It may have been up to 3 meters long.
Orthogenysuchus is an extinct genus of caimanine alligatorids. Fossils have been found from the Wasatch Beds of the Willwood Formation of Wyoming, deposited during the early Eocene. The type species is O. olseni. The holotype, known as AMNH 5178, is the only known specimen belonging to the genus and consists of a skull lacking the lower jaws. The braincase is filled in by the matrix and most of the suture lines between bones are indiscernible, making comparisons with other eusuchian material difficult.
Onchopristis is an extinct genus of sclerorhynchoid from the Cretaceous of North Africa, Europe, and North America. Its name is derived from the Ancient Greek ónkos and prístis. It contains two valid species, O. numida and O. dunklei, though some researchers argue that both may be considered a single taxon with variation in morphology caused by a wide geographical range. Specimens of Onchopristis have been discovered in coastal and fluvial deposits dated from the Barremian to the Maastrichtian age, making this genus one of the oldest and longest-lived sclerorhynchoid genera.
A neural spine sail is a large, flattish protrusion from the back of an animal formed of a sequence of extended vertebral spinous processes and associated tissues. Such structures are comparatively rare in modern animals, but have been identified in many extinct species of amphibians and amniotes. Paleontologists have proposed a number of ways in which the sail could have functioned in life.
Concavotectum is an extinct genus of freshwater plethodid ray-finned fish that lived during the Cenomanian in Morocco and possibly Egypt. It was discovered and named in 2008 and is known from a single well preserved hand-sized skull and a few isolated vertebrae discovered in the Kem Kem Group. The type species, C. moroccensis, was named in 2008 and described in 2010.
Richard Markgraf was a German Bohemian paleontologist. He is best remembered for his expeditions to Egypt, which discovered the first known remains of many extinct fossil reptiles, such as Aegyptosaurus, Carcharodontosaurus and Spinosaurus.
