540 Projects

A project is a themed assortment of media and specimens. Projects can be used to share media ownership and access between project members, and projects can also be used to publish assortments of media and specimens for access and discovery by the public. Examples of projects could include the 3D data used in a single research paper or a collections digitization project. If you want to share media ownership and access with multiple users across multiple projects, consider creating a user team. Projects can be managed by teams, and users with access to that team also gain access to any projects managed by that team.

Display all details of Baltorussus total makeover: rejuvenation and sex change in an ancient parasitoid wasp lineage The Orussidae is a small and rare but phylogenetically important family of parasitoid wasps. The fossil record of the family is also very poor. Baltorussus velteni was described from Baltic amber from an allegedly female specimen. This and another recently discovered specimen are examined with microCT scanning and standard microscopy. We reveal that both the holotype and the new specimen are actually males. 1 1
Display all details of K12 Human Evolution This project provisions scans of generic comparative elements of living species as well as iconic fossil specimens to illuminate patterns in human evolution. This project is designed to be used in conjunction with lesson plans available at Paleoteach.org (see link below) for k-12 educators. The digital models are made from physical replicas (rather than real specimens) in all fossil cases. The morphosource specimen numbers represent informal duke accession numbers for casts. The specimen number for the original fossils can be found in the description or notes sections. This may be important information when searching for additional contextual information for lesson plans. Educators interested in using these materials should also note that the scans are not 3D print ready, nor are they colored to indicate 'real' vs. 'reconstructed' regions of the fossils. 73 43

Display all details of Hyainailourine and teratodontine cranial material from the late Eocene of Egypt and the application of parsimony and Bayesian methods to the phylogeny and biogeography of Hyaenodonta (Placentalia, Mammalia) Hyaenodonta is a diverse, extinct group of carnivorous mammals that included weasel- to rhinoceros-sized species. The oldest-known hyaenodont fossils are from the middle Paleocene of North Africa and the antiquity of the group in Afro-Arabia lead to the hypothesis that it originated there and dispersed to Asia, Europe, and North America. Here we describe two new hyaenodont species based on the oldest hyaenodont cranial specimens known from Afro-Arabia. The material was collected from the latest Eocene Locality 41 (L-41, ~34 Ma) in the Fayum Depression, Egypt. Akhnatenavus nefertiticyon sp. nov. has specialized, hypercarnivorous dentition and an elongate cranial vault. In A. nefertiticyon the tallest, piercing cusp on M1–M2 is the paracone. Brychotherium ephalmos gen. et sp. nov. has more generalized dentition that retain the metacone and complex talonids on M1–M3. In B. ephalmos the tallest, piercing cusp on M1–M2 is the metacone. We incorporate this new material into a series of phylogenetic analyses using a character- taxon matrix that includes novel dental, cranial, and postcranial characters, and samples extensively from the global record of the group. The phylogenetic analysis includes the first application of Bayesian methods to hyaenodont relationships. B. ephalmos is consistently placed within Teratodontinae, an Afro-Arabian clade with several generalist and hypercarnivorous forms, and Akhnatenavus is consistently recovered in Hyainailourinae as part of an Afro-Arabian radiation. The phylogenetic results suggest that hypercarnivory evolved independently three times within Hyaenodonta: in Teratodontinae, in Hyainailourinae, and in Hyaenodontinae. Teratodontines are consistently placed in a close relationship with Hyainailouridae (Hyainailourinae + Apterodontinae) to the exclusion of “proviverrines,” hyaenodontines, and several North American clades, and we propose that the superfamily Hyainailouroidea be used to describe this relationship. Using the topologies recovered from each phylogenetic method, we reconstructed the biogeographic history of Hyaenodonta using parsimony optimization, likelihood optimization, and Bayesian Binary MCMC to examine support for the Afro-Arabian origin of Hyaenodonta. Across all analyses, we found that Hyaenodonta most likely originated in Europe, rather than Afro-Arabia. The clade is estimated by tip-dating analysis to have undergone a rapid radiation in the Late Cretaceous and Paleocene, a radiation currently not documented by fossil evidence. During the Paleocene, lineages are reconstructed as dispersing to Asia, Afro-Arabia, and North America. The place of origin of Hyainailouroidea is likely Afro-Arabia according to the Bayesian topologies but it is ambiguous using parsimony. All topologies support the constituent clades — Hyainailourinae, Apterodontinae, and Teratodontinae — as Afro-Arabian and tip-dating estimates each clade is established in Afro-Arabia by the middle Eocene. 0 0
Display all details of The sister group of Aculeata (Hymenoptera) – evidence from internal head anatomy The Aculeata comprises some of the best known Hymenoptera. Traditionally, their sister group has been considered to be the Ichneumo-noidea, however, recent phylogenetic analyses contradict this hypothesis. We evaluate three potential candidates for the sister group of aculeate wasps: Ichneumonoidea, Evanioidea and Trigonaloidea. This is addressed by investigating the internal head anatomy of repre-sentatives of the relevant taxa, specifically the tentorium, musculature and glands. One species each of the families Braconidae, Evaniidae, Gasteruptiidae, Aulacidae and Trigonalidae, as well as Sphecidae and Sapygidae as representatives of Aculeata, and Ibaliidae as outgroup is examined. 33 head anatomical characters are mapped on the three competing hypotheses. Aculeata + Evanioidea are corroborated by the presence of a secondary bridge, the presence of a subforaminal cup and the presence of one medial sulcus on the ventral head sclerotisation instead of two sublateral ones. Trigonaloidea + (Aculeata + Evanioidea) is corroborated by the presence of a bent cibarium. The presence of a hypopharyngeal gland, the backwards shift of the origin of the antennal muscles, the loss of the connection of the dorsal tentorial arms with the head capsule and the loss of ventral salivarial dilators are retrieved as synapomorphies of Aculeata. Two hitherto unknown glands, a hypopharyngeal salivary gland in Sphecidae and Sapygidae and a hypopharyngeal-maxillary gland in Evaniidae, are described. 7 7
Display all details of Gonzales Skull Project This project includes scans of strepsirrhine, platyrrhine and cercopithecine skulls that were collected by Lauren A. Gonzales for research on the inner ear (2014-2016). This work was funded by the LSB Leakey Foundation. Osteological specimens (for strepsirrhines and platyrrhines) are currently housed in collections at the American Museum of Natural History (AMNH) in New York, NY and also at the National Museum of Natural History (USNM) in Washington DC. All skulls were scanned at the Shared Instruments Facility (SMIF) at Duke University. All Chlorocebus skulls are part of a wild shot population from Rusinga Island, Kenya. Additional information, including body mass estimates, can be obtained by contacting Brenda Benefit (bbenefit@nsmu.edu). Acknowledgement that these scans are the property of the AMNH, USNM and/or Brenda Benefit is required for any publication resulting from the analysis of any of these scans. Cranial capacity for all specimens is available upon request. 477 200
